Calendar notifications not working on Mac Studio with Tahoe 26.1

Question

Calendar notifications not working on Mac Studio with Tahoe 26.1

Alerts / Notifications for Calendar not working

Mac Studio...w/Tahoe 26.1

I've noticed lately that Calendar has stopped sending notifications or alerts prior to scheduled events. Focus / Do not disturb is off. I also noticed that in Calendar settings, when I try and change the "Events" tab to say, "1 hour before", (in either On My Mac or iCloud), close the settings window and then reopen it, the events tab shows "None". Any thoughts?

Thanks

I found the answer. Apparently, after the last update (26.1), it looked like all existing events with reminders/alerts wouldn't post. Even after updating to 26.2 nothing worked. I added a new event with a reminder and it posted the reminder as scheduled. Looks like all pre-existing events might have been corrupted and need to be deleted and added again.
