Hello, currently I cannot dismiss calendar events on my GMail calendar within Thunderbird. I am being prompted every twenty minutes about an event from last week. The Dismiss and Dismiss All buttons on the reminder form do nothing. I am using Thunderbird 128.4.0esr (64-bit). The calendar is set up through Provider for Google Calendar version 128.0.0. (Doing nothing is an improvement over the built-in calendar, which threw an error message every time instead). This seems to be a persistent problem many users have encountered over the years, judging by past support requests from people with the same issue. Is there any way to dismiss these notifications? If not I will be uninstalling Thunderbird and finding a different email client.
