I'm curious what challenges you've faced on iOS -- for example, has Apple made it difficult to implement background sync?

We are still facing challenges with the reliability of background syncs on iOS. There is a threat of the OS blocking our background tasks altogether and we end up having to be very conservative when it comes to uploading data in the background. Which a lot of times results in 0 files getting synced until the app is in the foreground. These constraints don't seem to apply to Apple Photos though.
