Immich not syncing with multiple iOS devices unless in foreground
Hi I recently setup Immich on unraid - everything is working correctly and the web side of things is perfect. There are some massive threading/slowdown issues with the iOS app but I won't get into that.
The issue I have is that I have 2 iPhones (mine and my wifes) and an iPad Pro that I own, that are all setup for foreground and background syncing (also enabled background ability in iOS settings) and are all set to backup our entire collection (around 100,000 photos in total) over 2 different user accounts. When we're inside the iOS app, we can see that things, whilst awfully slow to interact with due to the upload, are syncing fine. I can also verify that everything is syncing correctly up with web side of things and everything is a-ok. The problem we have is that as soon as the app is backgrounded, the syncing stops.
I know from reading various issues posted already about this, that iOS has a scheduler and that the syncing happens sporadically. However, to test this, we've left the background processes running for multiple days to test and not a single Photo or otherwise is synced up during the period. As soon as the app is foregrounded, syncing starts again... so on and so forth.
Is anybody aware of the issue and is anybody looking to fix this? I have a very long road ahead of me to keep our screens on whilst it completes the task otherwise and presumable we're going to have an ongoing issue getting this to work for incremental backups also?
App version on all devices: v1.126.3
Server version: v1.125.7
