I have a problem with CalDAV calendars (supplied by DAVx⁵) in the Waze navigation app.
Here you can see a screenshot:
I can select the DAVx⁵ calendars in Waze to get notifications and also to plan my trip, but when I leave this screen everything is unselected again. Later I have found out that if I activate all calendar entries "Kalendereinträge (the first/basic calendar in Google or Android is called “Kalendereinträge” in German and also all DAVx⁵ calendars are named “Kalendereinträge”) they all stay activated. If I deactivate one, all get deactivated.
Also there is a problem that I do not see the real names of the calendars in Waze, but it works in other apps like aCalendar+ and also the Google calendar app. This makes it complicated to see which calendar is selected and which isn’t.
Btw, Waze works perfect with Google calendars. These selections and deselections work when leaving this screen again.
I have also addressed the bug in the Waze forum - who ask me to also bring it up here.
Looking forward for help and willing to give more information of needed and also willing to beta test.
