Where did the rest of the days in the calendar go?

[Android Central Question]

After the last software update the calendar on my S9 only shows sundays. No lines or dates devise the days, all white apart from previously scheduled events.
How can I get the days showing above again and dates marking the days?

Are you using a theme? That theme probably didn't get updated yet for the new Pie apps. Revert to the default theme.

Thank you thank you thank you! You were right and now I can plan stuff on the other weekdays too ;-)
