After a whole day trying to get this done, I give up.
I have 2 devices here, both Xiaomi Redmi Note 4, one of them works, the other doesn't.
On the device that doesn't, after appearing to sync fine, the Davdroid Group does not show up under Contacts. There's just the fuckin' google group I don't wanna use.
I tried: 126.96.36.199 (188.8.131.52 is not on F-Droid atm), and 1.4.1.
Calendars sync just fine.
It'll find changed address books (name, for example) just fine.
I made sure that all needed rights are there.
The bad one has the F-Droid version, the other one the GPlay version, is that making a difference?
Also the bad one does ask me the setup questions almost every time I open the app, as if it has problems persisting them...
The good one uses MIUI 184.108.40.206 Stable, while the bad one has 8.1.somthing, but I am in the process of upgrading it.
Anything else that comes to mind that could supress the contact group showing up?
