shared calendars do not hide confidential/private entries to other users. This PR should fix it: https://github.com/owncloud/core/pull/24080 would be great to get that in portage soon as well.

Hi, sorry it looks like this bugreport got lost/deleted in my mail queue. From the PR request, it looks like it is OK now with 9.1 and should not added in 9.0 as it would mess with database migration, is it right? In that case I mark that bug as fixed in 9.1.x ebuilds, don't hesitate to reopen if there is still something that can be done Gentoo-side (especially with 9.1 versions around now)
