I have been using the App for quite a while with my Mac Book Pro and two external monitors. So RDP was running on three display without any problems.
Since yesterday, it will only run on the main screen (sometimes also on the second screen).
While talking to our in-house IT support they were connected through Team Viewer, the App suddenly worked perfectly again on all three monitors.
The only obvious difference was that the man screen has slightly reduced its resolution for Team Viewer.
When disconnecting Team viewer the RDP still works, but it is impossible to reconnect to all monitors.
No updates on the Mac nor on the remote computer (Terminal Server) was made.
Thanks in advance,
