@ public: I was looking at this bug and wanted to chime in with this https://bugzilla.mozilla.org/show_bug.cgi?id=1768207#c18

I was having issues with my Android Calendar app seeing events my TB was not. I was almost certain it was Androi's calendar app that was at fault. Can you try what I mentioned in my comment 18 (re-edit the event in Android calendar and save it again) and see if it fixes it for you? I think a few Android Calendar app updates later and I haven't see the issue in TB since.
