it is several weeks now that I cannot close reminders in Thunderbird anymore. Or to be precise, I cannot close the ones that are for the-whole-day birthday appointments. Reminders for “normal” appointments can be closed.
So it seems to be related to the contact_birthdays calendar.
As I have not touched the Thunderbird settings in a long time (years since I added the Nextcloud calendar accounts) I am not sure if this is a bug in Thunderbird oder a bug in Nextcloud.
Anyone else experiencing similar issues?
Any ideas where to debugging?
(I checked the server logs but found nothing related…)
