READ AND RESPOND PLS

I had this app for so long on my iPhone and I loved it for the simple fact that we can look up videos on YouTube that might not be on yokees list and be able to sing it. Everything was perfect until I downloaded this same app on my iPad and it started working fine until I wanted to use it one day and YouTube wouldnt pop up with videos that I wanted to sing. Now I am entitled to only sing songs off the app .... why ?
