Not sure whether this is an android or a DAVDroid problem, maybe you can help me to narrow the possibilities.
1.) a Xiaomi Redmi 4X Device with Stock Android (no custom OS installation or modifications) with the latest DAVDroid installed (18.104.22.168-ose)
2.) I run a (tested) Radicale CalDAV Server at home and have installed the DAVDroid app (via F-Droid). Inside DAVDroid App, i have set up the connection to my CalDAV Server and DAVDroid shows up the calendar so the connection to the server is fine.
Problems occur when I want to use the CalDAV calendar with the “native” (i.e. stock) Calendar App of the Phone. In the calendar app I want (i.e. i have) to chose a “calendar account” but the DAVDroid account is not showing up in the list of available calendar accounts although it definitely exists.
(I did some other tests using the aCalDAV app and the aCalDAV account shows up in the list and is working with the phone calendar app).
Is there maybe a problem that DAVDroid has because it does not have permission to the system calendar storage? Any hints on how I could track down the problem?
Thanks a lot!
