Deleted calendar entries from a repeating event reappear
I delete and they keep reappearing as soon as I delete them. If I delete one (this event only) and go to delete another, the first reappears. For example, this means I can no longer make a single entry with all the details, repeat it, and edit the time of individual entries. It negates the usefulness of the calendar as a scheduling tool. It’s happening on my iPhone IOS 17.7 and iPad, and it just started this problem. Please help!
