Calendars turning off when I close the app
When I open the calendar app the calendars I had on have been turned off, I tap "calendars" select them, tap "done" and go back to view the calendar.
My calendar is now at 30 Oct 2019, but the calendars I selected now show, tap "today" and its all as wanted.
I close the app, open the app and 4 of the calendars I had turned on are now off.
It's always the same ones that go off.
Any thoughts?
