Since the clock change on the 29th the RD iOS app is not redirecting the correct time on the server. I can see this was fixed over summer in the macOS RD app, but it’s still in an issue on iOS.
I have the same from the latest iOS version on my iPhone.
I've reproduced the following: When you go into the time settings of the AVD and hit the "Adjust for daylight savings time automatically" slider, the slider "blips" (which seems buggy) and then the time rolls forward an hour and is then set correctly. Users can't change the time but this workaround allows them to do it themselves.
