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.
Got exactly the same situation. Users devices on IOS is 1 hour behind. It looks like it swapping the daylight and standard time the wrong way round when connecting via the iOS RD Client App.
Works fine on Web Client and Windows Devices.

Hopefully they can fix it soon.
I also posted on the AVD Community forum yesterday as I hadn't seen this post until now Time Redirection not working with iOS RD Client app - Microsoft Community Hub
