peter You cannot purchase ST3 without downloading it first. As the full version is an in app purchase that unlocks the full functionality in the already downloaded app. Please explain what you exactly mean.
Leonard All ok now , it wouldn’t unlock the free 6 song version now it does . I can put it on 3 devices ,correct? Thanks
peter There is no device limit. You can run it on all your devices that are running with your AppleID.
