my contacts are readded to my phones contact list, my favorite numbers are gone too.
I am syncing from android 6 to Nextcloud.
Before the upgrade I had one account in my android account settings, now there is one “Davdroid” and a “Davdroid-Adressbook” sync account. The adressbook account has the name adressbookname (accountname NQ).
I don’t know where the “NQ” comes from.
Should they be readded?
Yes, 1.5 introduced big internal changes in order to provide support for multiple address books per DAVdroid account. In the upgrade process from DAVdroid versions prior 1.5, contacts might be re-added completely.
