Interference with bleutooth apple mouse

Dear all

When I use Touchable Pro (V428) with ableton live 10.1
On MacBook Pro 2018 OSX 10.14.5

I experience recurrent disconnections then a few secs later reconnections of my bluetooth Apple Mouse.
When shutting down the touchable Driver+App all works back fine.
This is obviously Touchable Pro interfering with the mouse.
Very annoying !

Any help ?

My very best
