Please note that I am not reporting a bug, but asking out of curiosity.
I've setup DAVdroid to sync with my nextcloud server. I created one account and under this account there is a CardDAV (I've checked one addressbook) and a CalDAV service (I've checked two calendars).
What I do not understand is why there are 2 sync adapters for my addressbook.
- Address books
- DAVdroid Address book
So, there is
Address books and
Contacts. What's up with that?
