The bug

I have already backed up all my photos to Immich. Recently, I turned off iCloud Photos in my iPhone settings to clear photos from my device without affecting the photos stored in iCloud. Then I re-enabled iCloud Photos to sync everything back down. After the sync completed, all photos reappeared on my phone but with significantly reduced local storage usage.
However, after the iCloud sync finished, I noticed that most photo thumbnails in the Immich app are not displaying properly (while they display correctly in the web version). The Immich app logs also show "Error loading thumbnail" messages.

It seems that I have to reset my Immich app... but that way I have to again spend a lot of time hashing my photos

Hi @alextran1502, I've toggled on the beta timeline feature. For the logout and re-login method, I haven't tried as I've reset my Immich app, so I guess I have to take some time hashing all items again, then try to reproduce this error to validate if the solution is working or not.
