@cick0 Thanks for the instructions. When doing so, the event from Nextcloud 14.0.1 contains:
As you can see, it lists the same attendee (
email@example.com) twice (one time with status “needs action”, and one time with status “accepted”), and this is what DAVdroid synchronizes.
I don’t think DAVdroid should eliminate duplicates sent by the server… guess this is rather a server thing? At least in RFC 6638 there are no duplicate
Can you please report this to Nextcloud and provide this thread as reference?
