I have much the same problem. I cannot use the FBW Experimental or Development version because the MCDU will not connect on my iPad. It is NOT a connection problem as it works seamlessly and well on the stable version I have to use to enable the remote connection to work correctly. Whenever I try the experimental version, I get the MCDU outline only, the display window is blank. I know it is connected as the sound function is OK ! Attached are the latest versions I have and that is from the latest FBW installer. I cannot see how this is a connection problem as it works as it always has, on the stable version
