I'm syncing Lineage14 adress book by davdroid wiht nextcloud10.
Every time I edit any element of a contact on phone with the aosp contacts app, the sync of postal address for this contact doesn't work anymore.
To repair it, I have to delete the postal address element. Then do a sync, which removes the address from nextcloud. After this I can add the address element again by nextclouds contacts app and sync it to the phone.
Because of this behavior the address sync of a lot of my contacts is broken. There is no easy way to recognise the problem, because there are no failure messages.
I think the problem is the postal address handling of the aosp contacts app.
Would it be possible to patch the aosp contacts app?
Or is there another contacts app, which I can use without gapps?
