I had this same issue. I’m confident it is caused only by a lack of disk space, after removing a big video file, it immediately started working again.
Very interesting to hear. Didn’t know that little free space is a reason for not syncing. Probably the debug info should contain the free disk space, too.
Once I figured this out I realized that I’ve had this issue before, about a year ago. That time I also spent a few hours, very annoyed, not being able to find the cause of this issue.
Dont’ ask how many hours we have spent with that problem 😉 It’s one of the most frequent problems; and there is no clear solution for that. I would have never thought that the most complicated problem in app programming is to convince the operating system to actually start it.
I would very much appreciate it if the app would give any feedback on this. Why is there no error produced?
Because the sync is managed and started by Android. It should produce an error when it’s not able to sync. DAVx⁵ does not get any feedback or information that the system doesn’t fulfill its duties.
I would expect some kind of feedback when it can’t sync the calendars, right?
When DAVx⁵ would be started by the system, it could give some feedback…
