iOS 13 public beta: won’t play without black bars And not full screen. Tried tv settings and multiple TVs and adaptors. Crave app plays content full screen fine.
I tested on an iOS 12 device and it played fine.
First photo is iOS 13, second is iOS 12.
I tried an iPad Pro with iPad OS 13, and iPhone 8 Plus with iOS 13, and an iPhone 5S with iOS 12.
