What happened?

Ive subscribed to this app before and enjoyed the feature where you could search YouTube for songs not in the app. Now that feature is gone? All the songs I like to sing arent accessible now. Also, Id been paying for it and still couldnt save or share songs - kept getting the "oops" message. Very disappointed and Ill be cancelling my subscription now.
