Cant cast

I use this app with my chrome cast all the time but lately it just hasnt been casting. Every other app will cast perfectly, but this app just displays a black screen on the tv and continues to play on my phone. If the whole purpose for which I use this app is null, then whats the point? This app is awful, and seems to get worse with each update.
