Scenes are not starting from Ipad pro

Hello I am using currently a new I pad pro and detect that besides of all other controllers the clip activation from the pad is not possible. All other controller work fine also the scene activation, but I am not able to trigger a single clip
Astonishingly enough this is different with my older I Pad - same setup - clips can be triggered to start.
I am using this by now to control a Live latest 9 Version on a Mac Book Pro 10.10.5 Yosemite
Any ideas what to do ?
