Media Player is broken

So I was able to upload my song stems into the player and that was an easy straight forward process. I spent the extra $4.99 to unlock the full version. When I pressed the play button it played like it should, however, when I hit pause it does nothing, when I bring up the mixer after trying to pause it, I have no control over the mixer. After hitting the pause button I lose control over all buttons and the only way to get it to stop playing is to completely close the app. I like the app, I would like to use the app, but if I cannot pause it and then can’t do anything with it, then it’s not worth it even if it’s free.
