Two shared calendars vanished at one account, although they are correctly shared by other users

Hello, I use Nextcloud on my own Debian computer (stable) to share calendars with my family. For a few weeks now, sharing two calendars hasn’t worked and I don’t understand it. I have 5 users: our 3 children, my wife and me. All of them are in the “familie” group and my wife and I are in the “eltern” group.

Everyone has their own calendar and there is also a family calendar (Familie) which belongs to my account and is shared. The children’s calendars are shared with the “eltern” group so that we parents can see and write everything. Now my wife’s account no longer sees my calendar (Christian) or that of one of our children (Leander). Everything else works. These two calendars used to work for my wife too.

If I remove the sharing and then put it back in, nothing changes. Whether I share with “eltern” or directly with my wife makes no difference. If I create a new calendar and share it, it is visible to my wife. How can it be that these two calendars of hers are not visible?

My nextcloud version is 29.0.4.

Is there a file I can check? Is it possible, that some entry in some file prohibits exactly those two calendars?

I would really appreciate some help because I don’t know what to do. Otherwise I would have to create two new calendars and transfer all the appointments to them. :frowning:

Thank you,
Christian

Unfortunately I never had such an issue with my local set-up since I’m using Nextcloud. I cannot tell you what is going wrong here, but at leastI want to point-out that transfering appointments from one calendar to another should be an easy task by exporting and importing the calendar data.

One point which just came to my mind, you can try to reload the calendar app by pressing the “shift + reload” keys to make sure it isn’t any kind of cashing issue which prevents that the calendars are correctly displayed.

Thank you, the solution with exporting the existing calendars and importing them into new calendars work. Sharing of the new ones works without any problems.
