Seems to be an issue of the Android Settings app, as this only happens when re-installing DAVdroid while the Settings app is active. Is there anyone else having this problem?
Yes, I think you’re right.
I checked some other apps; all of them were synchronized on November 8th for the last time - which is exactly the date when the phone was updated to Android 6.0.1 Marshmallow. Therefore it might be a problem caused by this release!?
