Grand piano glitch, app hangs – Magic Piano by Smule Review

I love Magic Piano, but ever since the recent update, it hangs when I go to the Solo section and play the piano there. Also, the "Grand Piano glitch" where the app reverts the instrument sound to "Grand Piano" if I go to the app without turning internet connection on, or when I download a new song to play.
