In the standard calendar app my appointments are not displayed in the monthly view. Also there is no way to add any appointment in any view. No +button etc.

When I use Google Calendar from PlayStore everything works fine there.

Granted all rights to the Calendar app.

Does anyone have a suggestion where to go from here?

Thank you all.
