I have the same problem after november firmware update. YouTube 4k is broken, have no problem with lower resolution. Have no problem playing YouTube 4K content from other media. I can play 4K YouTube through the tv internet browser with no problem it’s definitely something wrong with firmware update and the YouTube app.Anyone having issues with with youtube tv? All I get is buffering. Its unwatchable. It works on every other device in my house.

Workarounds for Samsung Smart TV issues when trying to play 4K videos on YouTube, wherein the video keeps buffering and defaults to 360p.
After updating to the latest firmware, youtube now has issues. Before I had no issues whatsoever playing 4K60fps videos with a network connection of over 100,000 kbps and a healthy buffer....now it's constant loading and defaulting to 360P. Please look into it.
Youtube app on Q9FN continues to buffer to 360p. Apple TV app, Netflix, Amazon Prime have no issues streaming at 1440p and 4k. Youtube keeps buffering, tried resetting the app without any improvement. Anyone know how to fix this?
