Nope, I wasn’t notified by DAVdroid - possibly it was a too minor upgrade though it went the normal OTA upgrade way.
Will recreate my account, thanks for the help.
Syncing wit MIUI 8.3 doesn’t work. Even the workarounds in the FAQ about MIUI didn’t work.

It’s definitely a Xiaomi MIUI-issue. It works with vanilla Android. But i don’t know where to search for a solution.
Could solve the problem. It was an issue from upgrading to MIUI 8.3. You have to do a full wipe of the phone.
Here the steps to solve the problem:
Of course it will be a bit work, but it’s worth anyway. So always make a Backup and a Restore from the Xiaomi-App from time to time…
