My ipad recognizes the midi expression input (quattro) when I press a connected pedal, but the app does not fully open. It's stuck on "Detection may take up to 15 seconds. Please wait". I wait. Nothing happens. So I can't change the cc values for any of the channels. Are there any compatibility issues with IOS 15.4.1?
Incidentally, the app interface does operate correctly when I use the unit with my Windows computer.
