Package: evolution-data-server Version: 3.30.2-2 A couple of bugs are present which make CalDAV scheduling effectively useless - the combined effect of them is that everyone else shows as having your availability information, rather than their own.
I have patched the bugs upstream, and they have been merged into the branches for both 3.30.4 and 3.31.4: * https://gitlab.gnome.org/GNOME/evolution-data-server/merge_requests/8 * https://gitlab.gnome.org/GNOME/evolution-data-server/merge_requests/7 I'm hoping these patches could either be backported to the version in Buster before it's frozen, or buster can update to 3.30.4 when it is released. I have also submitted a patch downstream in Ubuntu Bionic, which backports to the older version of evolution they are packaging: https://bugs.launchpad.net/ubuntu/+source/evolution-data-server/+bug/1808264 Thanks
