Added calendar events not showing in Thunderbird calendar

more options

I have a hosted email service that I access via Thunderbird.

Currently, new events that I create do not show in my calendar.

I create an event:"New event">enter details etc>"save and close" and there's nothing there. I've synced the calendar. FYI, when I create an event via the web interface of my client, it appears in the calendar.

I'm using v115.2.2

Any advice?

An addition to this: - I've removed and re-added the calendar, the issue persists. - attendees I add to the event also do not receive any notification. - weird, when I set the event to "all day" it will appear in my calendar. If I set the time/duration to anything else, it does not appear. Editing an "all day" event to (for example) 12-1pm doesn't make it appear. - this is for Win11
