hi, thanx for your reply!
the event is a birthday of a friend. 1979 is the birth year. i remember that i changed this event recently only to remove the reminder. i don’t remember where exactly did i change it, there are three possibilities: 1. Etar calendar app on my phone dvice, 2. Fastmail web calendar and 3. Gnome calendar on my laptop. It was probably 1. or maybe 3.
the recurrence is always set to forever, so the 1970 end date should have been set as a part of a bug somewhere on the road.
but it seems because of this event no other event can be synced from my phone to Fastmail server. i’ll try to delete this one (and set it later as new) to see if that change something.
i deleted the event and was imediately able to sync my device calendar again. a few other events that i set on my computer and were previously unable to sync were synced to my device now.
do you think there’s something you can do on DAVx5 side so that one false event wouldn’t block syncing other events?
thanks for your help again!
PS - although i have DAVx5 installed from F-Droid i also bought it on Play Store to support your great work.
