[Evolution] Evolution CalDAV calendars marked read only. CardDAV does not work.

[Eric O'Connor <eric oco nnor org>]

I have configured my calendar, and can view all of my events, but
cannot edit it within evolution. Is there a solution? 

This appears to have happened before, was it fixed and then reverted?

Is CardDAV supported at all? It's referred to as "webdav" in the
address book menu, so I'm not sure if I should be expecting things to
work out, since the two are different things.

This is on 3.22.3 (default in Fedora 25).

Thank you for any tips!
