I have used DAVx5 on my Huawei Mate 20 X for a couple of months now and it is working fine.
But when I installed it on my new Samsung Galaxy Tab S5e (Android 10) and LG G8X ThinQ (Android 9) this week, the CalDAV calender from my Mailfence account does not show in the calendar list , only the CardDAV at the contacts.
I have tried re-installing DAVx5, clearing app data, cache, removing account and re-entering but it does not show up. App permissions are set correctly.
So I looked up other CalDAV apps in the Play Store and found OpenSync. This looks suspiciously like DAVx5 and has not been updated since April 2017 but this does show the CalDAV with the exact same account details.
When I manually try to create a Calendar in DAVx5 the Storage Location shows up correctly but I get an error when I click CREATE.
So I think my issue has to do with DAVx5, right?
