ive been trying to integrate more options to Nextcloud since i have the resources on the server.
ive been able to sync icloud contacts but now im on a search on how to get the icloud calendar to update on Nextcloud.
currently ive made my icloud calendar public as read-only and if i subscribe in Nextcloud, i see the existing events but if i add a new on on the original icloud calendar it will not update on Nextcloud.
I have in mind that ical calendars are not requested by the server itself, but handled by your web browser. That would also explain why updates are only displayed after a new login (or after pressing the F5 button to reload the content).
