Since version 115.2.1 and now with 115.2.2 I do have severe problems with calendar, especially with invitations. Per example, I invite another person, this person won't get an invitation and on the other hand I do get an answer for myself, that I accepted the invitation. Very weird!
For me, at the moment, calendar is almost useless. Hope really that the next update will fix this!
If any of you guys has any ideas for fast fixes of this problem, please let me know.
Indeed, invitations stopped working recently.
It looks to me that the first person on the list gets invitation while others don't.
Also, when I select contact to add, sometimes it is added twice on the list.
