I've been gradually getting up to speed with Mozilla Thunderbird running on Windows 10, and I've encountered a mystery.
I received an iCal invite via Thunderbird, and attempted to share it to my Google Calendar by linking my Google account to Windows 10. But when I completed this, the invitation showed up not on my Google Calendar, but instead on the Windows 10 calendar.
I would have thought that using a Google login would have propagated the meeting to Google's calendars. Am I doing something wrong?
