Watching youtube using cellular data on Apple TV

I'm trying to use my unlimited data plan on my cell phone to watch Netflix and YouTube on Apple TV. Whenever I try this I get an error saying "An error occured loading this content. I have set my iphone 6 plus wifi up with static IP, and I can watch a slideshow and do screen mirroring, but when I try to watch a video I get this error. Has anyone got any ideas how to do this? I have unlimited T-Mobile data and no internet service. I just want to use Apple TV to show the Netflix, etc.

The YouTube app on the iPhone doesn't AirPlay or screen mirror... If you have mobile hotspot/tethering on you cellular plan with T-Mobile, use your iPhone as a wifi hotspot for the AppleTv to connect to.

rick, did you ever figure this out? i have the same situation and i'm guessing you didn't want to rely on the mobile hot spot option since it's capped.
