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.
Apologies, I have updated the RD Client to version 10.5.2 and the bias and boundaries have updated. However the daylight boundaries are different for the M, D and DoW compared to the RDP client on Windows.
