Any reason why YT 4K doesn't work on the iPhone X yet? It's OLED and HDR-capable so it seems strange to leave this model out.
Codec wars, ok thats hyperbole but afaik Youtube use VP9 for the higher resolutions but Apple won't use VP9 they use HEVC, so no high resolution on Apple devices (at least until possibly the next round of software updates, ios14 etc?)
We need to wait until Youtube and Apple play ball, or they both switch to the next codec, not sure what that will be.
