Can I ignore this message or is something wrong?
The server has reported that a resource couldn’t be found, so synchronization is aborted.
See logs for details. This is a probably server problem.
For now I tried Samsung Calendar and Contacts and Google Contacts, no DAV accounts visible, tried also saving to device hoping it will get synced but it didn’t either
In system settings>accounts everything looks just fine
You need to select an address book and a calendar, then press the Sync button. Then they will appear in the system accounts and in your used apps such as SPlanner etc.
@devvv4ever thank you, I couldn’t figure it out myself
