At first i like to say that my problem start with the last update DavDroid 188.8.131.52 -> 1.1.1
Now i am back to version 184.108.40.206 and it works perfectly.
The server is owncloud 8.2.5.
I have a android 5.0 device and there 2 DavDroid-accounts only for calendars. The contacts are synced with CardDav (sorry but this is because of the problem with the fotos last year).
Now the problem with version 1.1.1:
I have 2 accounts, account 1 has 3 calendars calA calB and calC, and account 2 has 2 calendars calD and calE.
I create on the andoid-device the first account and it find all 3 calendars calA calB calC, perfect.
Now create account 2 but this will find the same 3 calendars from account 1 (calA calB calC) and not its own calendars (calD calE).
I delete everything and install the old version 220.127.116.11 and create both accounts and it works perfect.
My wife with an android 6.0 device has the same problem with account 2 and account 3. It depends on the first account that i create, the second account will get the same calendars like the first account.
If you need settings and debug-info: now i have 18.104.22.168 installed, if no other user has this problem then i will install 1.1.1 again and send this information
Can someone help ?
