I previously used my Audio Interface Yamaha AG06 with an iPad and Cubasis LE 2, then I sold my iPad, bought a MacBook Air and an iPhone SE 2020.
So now I have Cubasis LE 3 on my iPhone, it’s shown as activated in my Steinberg account but the iPhone app still works in Demo mode only and request a bluetooth device: why is it so and what’s to be done please?
