I installed Superman 3.0.1 recently, and sync isn't working.
It all started Please login to see this link.. I then found out that Firefox was also not syncing, but when I hit "sync now", it actually forced a sync, and a toast was displayed "auto-sync timers have been started". This actually seems to have been issued by TaskWarrior, as that's Please login to see this link.. Shortly afterwards, Firefox synchronised, and so did DAVDroid, at least partially.
Unfortunately, my device switched between access points during a subsequent sync, and since then, syncs have no longer been working, and I also cannot get Firefox to sync at all, nor can I get this "auto-sync timers" message back.
Do you have any idea what the issue could be? Could this be related to your ROM? It was working fine for days (after the new install), and then just stopped two days ago. Not sure what I was doing then…
Is it possible that there is something like a sync thread on Android, and those are somehow not running properly? How could I fix that?
And yes, I've rebooted the device several times to no avail
