Nextcloud version: 12.0
Operating system and version: iOS 10.3.1
I have this simple problem, but I don’t know where to start to debug it: on an instance of NextCloud with 5 calendars, 2 of them don’t get synced on iOS. They appear in the list of calendars on the iPhone, but events on this calendar don’t show up. It is not related to their shared status (one is shared, one is not, and other working calendars are either shared or not).
I have no clue if it is related, but I noticed the discrepancy after I switched to HTTPS… I have already deleted the account altogether on the iPhone to start from scratch, and updated to NextCloud 12.0 to see if it would make any difference, to no avail.
Any idea where I could start to fix this issue?
Note that all calendars are working without any problem in the Calendar app as well as on Thunderbird/Lightning, so it might be an iOS issue, not a NextCloud issue. Still, I’d be happy to have pointers to resolve the issue.
