Fully functional again! READ THIS.

If you are having trouble strumming or placing 2 or more fingers on the strings and playing its probably because you have the zoom function enabled on your phone. You can tell if this is enabled by tapping on your screen twice quickly with 3 fingers.

In order to use this app fully, go to your Settings > General > Accessibility> then turn Zoom off.

Now that I figured this out, Ill be using this app all the time again!
