Game Streaming

I recently got accepted into Project Xcloud, and i wanted to rry out streaming because i was about to go on a 40 minute drive with my mom and wanted something to do. So i load up a game, get it loaded up, and i try to scroll down. For some reason, the
only buttons that works while im streaming to my phone are the A and the button to the bottom left of the home button. Is this a common issue and is there a way to fix it?
