YouTube app HD buffer

Hi.i have WD tv live streaming media player,which I’m not sure which generation is it,but I decided to use it again after awhile, updated to 2.03.20 firmware(which I assume is latest firmware),I have no issues playing HD files from my USB but YouTube app is super slow and won’t play more than 240/360(and I have fast internet).when I change to higher quality it there any solution,I saw you can use apps on USB,but I don’t see tutorial for it,can anyone help me out.thanks in advance

The only solution is to use hardware that’s not a decade old, obsolete and discontinued.

I can stream Youtube up to 4K Resolution on my Smart TV and Games Console with Zero buffering.

I have fast internet too, which is not bottle necked by old, obsolete hardware.
