#gnome now works with Fastmail (npub1n8z…jgru) via webdav on #ubuntu!
Previously, I had to manually add each of my calendars to the GNOME Calendar app, but now with this update, I can just setup my DAV account in GNOME Settings and it will automatically find my calendars, contacts, and even files (which I never use and thus disabled).
