Fixes#319 — Server appears as "undefined" on Samsung TV after network interruptions
when using mDNS (.local) hostnames.
Root cause:
The injected jellyfin_credentials in localStorage were missing the `Name` property.
When the TV couldn't reach the server (mDNS resolution failure), Jellyfin Web had
no cached server name to display, resulting in literal "undefined".
Changes:
- Add `Name` property to injected auto-login credentials using the real ServerName
from /System/Info/Public, with fallback to the server URL
- Store JellyfinServerName in AppSettings (fetched during server validation and
authentication, cleared on logout)
- Add the server's LocalAddress (IP-based) as a fallback entry in config.json so
the TV can still connect when mDNS resolution fails
- Add a visible warning banner in the UI when a .local hostname is detected,
advising users to use a direct IP address instead
- Add lblMdnsWarning localization key to all 28 language files (translated for
da, nl, en, fr, de, pt, tr — English fallback for remaining languages)
Description
Fixed UI freeze when update dialog appears during startup. Previously, network scanning and GitHub release loading continued running in the background while the update dialog was displayed, causing the window to freeze.
Changes:
- Added _initializationCts to cancel initialization tasks
- Pass cancellation token to LoadReleasesAsync() and LoadDevicesAsync()
- Cancel background tasks before showing update dialog
- Resume initialization after user dismisses dialog (Cancel/Skip/Manual)
- Added cancellation check in DeviceHelper.ScanForDevicesAsync() loop
Summary
- Add auto-update checker using GitHub Atom feed (bypasses API rate limits)
- Show update dialog on startup with two options: "Open Releases" (manual) or "Update Now" (automatic)
- Automatic updates: download, extract, replace files, restart app
- Support for Windows, Linux, and macOS
Changes
- New services: `UpdaterService`, `UpdateDialogService`
- New dialog: `UpdateDialog` with version info and release notes
- New settings: `CheckForUpdatesOnStartup`, `SkippedUpdateVersion`
- Localization: All 6 languages (EN, DE, NL, FR, DA, TR)
Technical Details
- Uses `/releases.atom` endpoint instead of REST API (no rate limit)
- Falls back to API only for download URLs when update is available
- Update script handles file replacement while app is closed
- Version comparison with semver support
Users with Jellyfin servers configured with a base path (e.g., http://ip:8096/jellyfin/)
were unable to authenticate. The "IP : Port / Full URL" mode didn't include a base path field, and
while "Full URL" mode worked, it wasn't intuitive for this use case.
The server validation (/System/Info/Public) succeeded, but authentication failed with:
'<' is an invalid start of a value - indicating the API returned HTML instead of JSON
because the base path was missing from the auth endpoint URL.
Fix: Added a third server input mode "IP : Port : Path" that allows users to enter
protocol, IP, port, and base path separately.
CSS Style Tab
- Theme preview images are now clickable - opens the theme's GitHub README page

- Fix dark mode for all modal dialogs (BuildInfo, InstallationComplete, Installing, IpInput, TvLogs)
- Update DialogService to use theme-aware colors from FluentTheme resources
Summary
- Remove UpdateMode dropdown from Server tab - settings are now always applied via JS injection
- Remove User Tab completely - these settings are default in Jellyfin and API calls are unnecessary
- Simplify JellyfinPackagePatcher to always apply server settings when JellyfinIP is configured
- Remove UpdateUserConfigurationsAsync API method and InjectUserSettingsAsync HTML injection
- Clean up related constants, AppSettings properties, and localization strings (6 languages)

- Localization: Added lblRefreshUsers and lblUserSelectionHint (6 languages)
Behavior
- Admin login: Shows user list with multi-select, "Refresh" button, configures all selected users
- Normal user login: No user selection UI, only own account is configured
- Auth status shows "Authenticated (Admin)" or "Authenticated"
Summary
- Removed obsolete Legacy API Key system - authentication now uses AccessToken from username/password login exclusively
- Removed user dropdown (LoadUsersAsync, AvailableJellyfinUsers, SelectedJellyfinUser) - no longer needed since you authenticate AS a specific user
- Removed "everyone" code path from TizenInstallerService
- Fixed server input mode not persisting after restart (Full URL mode would reset to IP:Port)
- Added Logout button to allow switching Jellyfin accounts
Changes
- JellyfinApiClient: Removed `LoadUsersAsync()`, updated auth to use AccessToken

The Settings window now has 5 tabs: Main, Server, Playback, User, CSS Style
Fixed bug where closing the success modal after installation would shut down the entire app instead of just the modal window.
- Changed CloseWindow() from desktop.Shutdown() to RequestClose event
- Window now properly subscribes to RequestClose and calls Close()
Summary:

Server Tab now has 3 sections:
1. Server Settings - Update Mode, Input Mode, Server URL/IP, Connection Status
2. Auto-Login Settings - User, Password, Authentication
3. Advanced Settings - TV Debug, Server Scripts, YouTube Fix
User Tab addition:
- Added "Legacy API Key System" section at bottom
- Moved API Key field and Jellyfin User(s) dropdown here
- These are legacy features from WPF era, kept for backward compatibility
### Bug Fixes:
- Fixed ServerMismatch breaking auto-login - The auto-login credentials were using a fake server ID derived from the URL (serverUrl.replace(/[^a-zAZ0-9]/g, '')). Now fetches the real server GUID from /System/Info/Public endpoint and stores it in AppSettings.JellyfinServerId for correct localStorage credential injection.
- Fixed URL handling for reverse proxy setups - URLs without explicit ports (e.g., https://xx.seedhost.eu/xxx/jellyfin/) now work correctly. Default ports (443 for HTTPS, 80 for HTTP) are no longer included in the stored URL.
- Auto-enable config patching on login - When authentication succeeds and Update Mode is "None", it automatically switches to "Server Settings" to enable
config patching. Removed the unused EnableAutoLoginConfigCommand button.
### UI Improvements:
- Reorganized UI with TabControl - Split settings into 3 tabs:
- Server: Server settings + Auto-login settings
- Playback: Browser/playback preferences
- User: User-specific settings
- Server Input Mode selector - Users can choose between:
- IP : Port mode - Enter protocol, IP, and port separately
- Full URL mode - Paste complete URL (auto-parses all fields)
- Removed Base Path field - No longer needed since Full URL mode handles paths automatically
- Improved button consistency - Test Server and Test Login buttons now have matching sizes and styling
- Label updates:
- "Status" → "Server Status"
- "Test" button → "Test Server"
- "Login" button → "Test Login"
### Localization:
Added/updated translations for all 6 languages (en, de, fr, nl, tr, da):
- lblTabServer, lblTabPlayback, lblTabUser
- lblServerInputMode, lblServerUrl, lblConnectionStatus
- lblAutoLoginUser, lblTestServer (updated)
### Modified files:
- JellyfinConfigView.axaml - Complete UI restructure with tabs
