I make copious use of the ‘Clear All Notifications’ action, so it won’t bother me. (But I only have notifications for events/reminders in Fantastical, not Calendar.)
I’ve not used “Clear All Notifications” so I have a question:
Is it tailorable so only notifications from a particular source are cleared out? I wouldn’t want collateral damage - so unrelated notifications disappeared.
Nope. It is a very blunt instrument. It will clear all notifications. So I only use it after I have scrolled the entire list and made sure there’s nothing I want/need.
