Review for Provider for Google Calendar by Antonio M
Rated 5 out of 5 stars
I've exactly the same problem than Tom Leonard. I can syncing to receive events, but i cannot send to Google Calendar from Thunderbird with lightning.
*UPDATE!*
As mentioned by Snow99, the Workaround to TB Update 52.0.1 by Nighthawk published on April 27, 2017, WORKS! THANKS to both you.
