Review for Provider for Google Calendar by Richard Scoville
Rated 5 out of 5 stars
I think this has already been noted - events entered directly into Google Calendar sometimes fail to appear in Lightning calendar - some appear to be delayed, some fail to show up at all. Hope you get it fixed - this app is a core part of my work setup.
