Using this addon, I had the unhide/hide after sync bug and I also couldn't accept invites scanned from my emails.

I took the advice from another reviewer and instead used the approach detailed here: https://www.ubuntubuzz.com/2017/07/how-to-setup-thunderbird-for-google-calendar-caldav-read-write-access.html to setup read-write access.

This approach worked perfectly, and I can use all the lightning features in my google calendars with no issue.
