Snooze not working on iOS 13

Not sure when it happened but snooze on the calendar is not working on the latest iOS 13.3.1 - anyone else having this issue?

I did raise it with support as it did snooze for 15 minutes a while back but they couldn't help. I also suggested to support to allow more options like 5 or 10 minutes like you can on the PC. They said to raise it as a suggestion, which I did but that will never happen unfortunately.
