Can you press "back" on Windows based room system?

[Petri-X]

Hi,

Have others noticed that if you press "call" on the screen, you end to the following screen:

If you try to press "back" on here, that makes no action. Only option is to wait that device realize that you are not going to do anything, then it goes back to the main view.

If you type name, and make the call, that is working fine.

Working on my device, I'm guessing the app is up to date.
