Great device, app almost unusable
I’m in love with my new Jamstick and it works fine in GarageBand but your app is quite slow, doesn’t open on my iPhone SE while on my iPad Pro very often even after my Jamstick is connected and selected the exercise buttons and the play button on the main menu stays grayed out therefore I can’t use the app. As a working programmer I’m sorry to say that while the device is amazing the quality of this app isn’t good even for an amateur.
