Same problem the bluetooth connection is not the problem for me either it is the app continually says connection lost but when I look at the bluetooth connections is still sits there as connected some times shutting down the app completely by double clicking the ipad button and swiping it away then restart the app and it reconnects but other times I have had to shut down everything and start again even to the point of restarting the iPad. I own both a 75 and 150 just cannot trust them in a live situation. Don't get me wrong I think the amps are grate sounding and the modeling out of this world. just flat fun until this occurs. It is my firm belief that the app is the issue and not bluetooth or amp itself
