OK, TB is driving me crazy with two Zoom events (plus others in the past that I just had to delete because they were so annoying.) Whether I click "Dismiss All" or click on the individual event and "Dismiss", they pop right back up. Same thing happens when I try to close the window. I have removed mail extensions (Provider and another that I can't remember the name of), deleted the calendars, restarted TB, and added the Google Calendars again... but they still pop up. And, again, this seems to only happen with Zoom events but not all Zoom events... not even all Zoom events on one calendar. Finally, the calendar is not set to Read-Only. This is driving me crazy because not only can't I Dismiss them, they also beep every five minutes. Right now I have to disconnect the Calendar before I lose my sanity.
