Event end time is wrong when timezone GMT+1

Currently in the UK we are using GMT+0 timezone.

From late March 2023, we will change to summer time which is GMT+1.

Using this plugin, I created a zoom event in April 2023, selecting timezone GMT+1.

Meeting start time: 11:00

Duration: 1 hour 30 minutes

So the meeting end time should be 12:30

In Zoom, the meeting is created with the correct start and end times. But on WordPress, the meeting times are displayed as 11:00-11:30. The end time is one hour off.

Is this something you have seen before, and what is the solution?
