can no longer sync after upgrade

[osfe]

Hi there,
I recently upgraded davdroid to the new 1.6.1. Since then I can no longer sync contacts and calendars.
I tried remove and reinstall of the app. I tried to reset my entire system and reinstall davdroid, but nothing works.

here is the log

I also followed the instruction on this page:
https://davdroid.bitfire.at/faq/entry/miui-no-synchronization/

Also, the davdroid account does not appear in calendars, meaning I can’t choose the davdroid calendars in the calendar settings.

can you please help me

Thank you very much for your time and consideration.

regards,

Olivier

Just to let you know, without doing anything more, it now syncs… I don’t understand but I’m glad it works.
