Somewhat similar thing I didn’t like with the free version Cubase IC. When I don’t need IC I want to put iPad in sleep so the battery is saved. But when I wake iPad, it looses the connection and I have to restart the Cubase. I tried to reset in ski setting within Cubase. But no use.
I thought in pro version it should be different and work as I thought it to be. But you seem to have same issue. Am I right?
