I have a BlackBerry KeyOne and the Contacts app has been causing me problems recently. Any address books that I'm using CardDav with to sync are not syncing properly with the BlackBerry Contacts app. However, they sync perfectly fine with the built-in Google Android application.

Anyone else have this problem and how did they fix it?

Maybe check your server settings for the account.... https://forums.crackberry.com/showth...1#post13030283

Use the info from the built in app to match to the BlackBerry Contacts settings for this same account.
