@equaeghe Happy to hear that it now works for you. I recommend the default setting of 90 days into the past, which provides a good balance between availability of recent events and traffic/performance.
Crash on account addition
I updated from 0.9 to version 1.0 yesterday. The upgrade itself went well, but my tasks disappeared. So I decided to reset everything. I deleted OpenTasks and DAVdroid completely.
Now I cant add the account anymore, as DAVdroid crashes.
I also entered a wrong URL at the beginning, which DAVdroid does not recognize and tries for ages finding a working server on the invalid URL. I killed DAVdroid to abort.
I use Radicale, which is fully functional (worked with 0.9 and with Thunderbird/SOGO plugin).
I have identified the missing null pointer check and it will be fixed in the next version.
However, this problem should not occur if you use the correct initial URL which should have a
current-user-principal. Maybe you just need to append a slash (don’t know your Radicale configuration)?
The slash did it. Thanks for fixing the crash!
