Review for Provider for Google Calendar by Old-School
Rated 1 out of 5 stars
Worked fine until I shut down Thunderbird. After that it would not sync with Google Calendar at all no matter what I tried. I uninstalled it, and set up Thunderbird 115 to use a Network Calendar with Google Calendar. This works fine and no sync issues.
