TeamViewer Host android cannot be controlled from OSX TeamViewer 12

Hi, I'm using TeamViewer12 on an osx sierra to connect to an Hauwei P7 using teamviewer host app (12.0.6197 with huawei plugin 11.0.5441)

If I connect to the android device from the osx "remote control" page remains white without showing the device screen.
If I connect to the android from another android device remote control works fine
