I’m using DAVdroid for a while now and am quite happy with it 
Since a couple of weeks I’m getting these tiny alerts though when syncing the calanders. I think I must’ve edited one of the contact birthdays by accident and now it’s trying to write to a readonly calendar.
How can this be prevented?
How can I mark the calendar as readonly? In the list of collections below none of the calendars is marked as such.
Thanks for your help!
