Google and CalDAV Rated 2 out of 5 stars
Google and CalDAV only partially works. Calendar has "momentarily not available", but will still sync one event at a time if I press synchronize. After restart no events are visible again and have to press synchronize a bunch of times.This review is for a previous version of the add-on (1.9.1).
This might actually be a Google issue. I have similar symptoms for the beta version, all other CalDAV servers seem to work.
