No task bar on Android... ah, I'm using a phone, not a tablet or Chromebook.
I get the idea it happens when I haven't been using the app. For example yesterday it was listed in the log around 21:45, whereas I hadn't opened the app all day, my sync jobs we're scheduled at 22:00 (but not expected to run as I'm given to understand background sync is not yet implemented). When I opened the app around 22:30 they ran just fine (per the Start sync after app starts setting). The Sync jobs are set to run every 20 hours, but had the app actually automatically done that in the background, that would've been around 21:05.
Looking at the logs again, it did actually start all sync jobs around 21:40, listing Shall sync and Starting sync entries but never Finished sync. Which I can confirm, because before manually opening S3Drive at 22:30 I compared the contents of my local and remote backup in another app and changes had not been synced yet.
However, the "Rclone initialization failed" entries that started at 00:40 and stopped at 00:50 (so lasted 10 minutes) were NOT preceded by any sync events.
I don't have Media backup enabled at all, but I did try it out earlier, including Background backup. It's now disabled, but it still has a now non-existing album listed as selected, since the app complains when you remove the last album.
I can't get a good understanding of when the app syncs and doesn't sync, but I haven't mentioned it before as I assume it's still a work in progress. For example, I have sync job A set with an interval of 20 hours and Start sync after app starts is enabled. In my testing, when still within 20 hours after the last sync, new files will not be synced when opening or even restarting the app. They will when opening the app after the 20 hours have expired.
Then at other moments I tested, it actually synced upon starting the app, regardless of how long ago the last sync had taken place.
