Yes I often have 30 min events at 11:30pm. They used to not show up at all on the iOS app but they now show up as an all-day event. Also not sure why there's an extra all-day event called Reading - I don't have that in my calendar haha and my other all-day events aren't showing.

Oh that’s no good!

Having a hard time reproducing this on my end. Is it an event specifically between the time? So 11:45-11:50pm or something that goes into the next day like 11:45-12:30am

I just realized for those events that go into the next day they appear as “all day event” at the top so need to fix that.
