DAVdroid v 2.0.4
Blackberry Keyone, Android 8.1.0
Synology DSM, CardDAV Server 6.0.9-0087
Installed as recommended: https://www.davdroid.com/tested-with/synology/. After (multiple) sync’s the BB Contacts app still shows no contacts. When creating a new contact in BB Contacts app it can be saved, but does not show up. However, the newly created contact is sync’d to CardDAV server and my laptop (Windows/Outlook).
Have used the BB CardDAV-account with the same settings for comparison and contacts were sync’d (problem here is that I can open a contact just once and any further time I want to open I receive the error “contact does not exist”). Have also tried CardDAV-Sync free for comparison and this app works as intended and w/o any problems. Still want to stay with DAVdroid if a solution can be provided.
Thanks in advance for your support.
