Setup nextcloud last week.
After some trouble with davdroid prior Version 1.1.1, one account on a device looks fine. Calendar and Contacts from Nextcloud synchronize without problems.
Create a second account on same device looks fine at first moment. Diffrent named Calendar and Adressbook will show in the new Account.
After create the new account davdroid throws Exceptions with sync problems.
It looks like to try sync resources from the other account.
The Notification can be found here
Thanks in advance
