Synchronization unreliable

Now and then, there are sync issues on Android 15+. It only seems to affect some people, sometimes it goes away by itself and we have not been able to reproduce it ourselves.

It would be interesting to log more information on the workmanager status

Finally I was able to see it for myself. I did not have a debug version installed though, so will do that now and hopefully catch some of the new workmanager stop reasons in the log the next time it happens.
