AVPlayerViewController on iOS 11 device not being able to AirPlay to AppleTV

I have this app using

AVPlayerViewController

I run this app on an iPad 3 with iOS 9.2 and it is able to airPlay to my AppleTV running tvOS 10.2.2.

I run this app on an iPad Pro with iOS 11 beta 9 and when I tap on the airPlay icon on the video control the only thing the app does is to expand the player window and the bar itself.

When I tap again on the airplay icon, the bar is all mangled (see the following pictures).

BAR STARTS SMALL

BTW, the back 15, forward 15 and pause never works at any point.

Is it just me or is this a iOS 11 bug?
