iPhone Winadmin

I just purchased an iPhone and downloaded the Winadmin app. However, when I try to connect to my company's terminal server all I get is a blank screen.

I can login in using RDC without any problem. Also, the terminal server is set to allow access to any rdc (less secure).

Also, I have no problem getting on the internet with the iPhone.

Please help.

sounds like display resolution issue, also make sure to update the software to latest version.

I have downloaded the latest version, 1.1.1.

Also, I have the resolution set to the same as the terminal server. I have also tried other resolutions without success.
