Apple has a fix for that. Background uploads from apps like Immich are tied to how often you open the app. So if you’re not constantly opening the app you rely on for sync, it’ll silently fail and you won’t notice. So 3rd party apps feel unreliable when compared to Apple’s solution.

Apple, Google, and Microsoft act like ransomware gangs when it comes to photos. I hope we see the day where all 3 get split into a thousand different companies.

Edit: I just checked and my photos stopped syncing 14 days ago. Thanks for the garbage Apple!!
