YouTube banner

The YouTube banner is making it impossible to launch the workout to full screen from the website. You can’t exit from it n can’t click around it. So stuck watching this on a much smaller window. Every time I try to click around it to expand the screen it takes me to YouTube n loses the video I wanted to play. Very frustrating. I know I can watch it through YouTube directly but I like interacting with the video through FBlenders site. This is new with in the last 3 days. What can I do?
