When using Nextcloud Mail, it’s unclear if Nextcloud Calendar (NCC) supports Google Calendar meeting cancellations.
When a Nextcloud Calendar user, who is already has a Google Calendar based appointment invite in their calendar, receives a cancellation from the organiser, Nextcloud calendar doesn’t remove the appointment from the Nextcloud users calendar.
I’ve tested this today. I received a cancellation for a meeting, used the Netcloud Mail UI (share icon at bottom of the mail- import into calendar - choose calendar) to “cancel” this appointment.
When I look in calendar it has not been removed.
I’m unclear where this issue lies - if Nextcloud mail, or Nextcloud Calendar.
I’m happy to test more.
