After installing tvOS 11 both the testflight beta and release both crash swiping down from the menu on On Now, Guide, and Recordings. DVR, Search, and Settings are fine.
Thanks for reporting. We have no plans to support tvOS 11 until atleast beta 3, as early builds are nototoriously buggy.
Turns out this was an easy fix, so this should work in the latest beta.
It works, Thanks!
