are you using chrome?
absolutely. device doesn't matter. internet connection doesn't matter. it's all https (google knows how to make sure their sites are save). change browser and BAM all works perfect.
they made sure youtube never worked properly on wp7, 8, w10m, too

as far as i know (but i havent' tested. most of my youtube is through 'mytube', a 3rd party app, or through embeds anyways, they work fine), as far as i know, they atm use some chrome specific api that fails on other browsers, so it's hard to spoof it.

this thing on making youtube work horrible on microsoft products so you chose google products instead is a thing i watch for 10 years now. it's absolute bullshit. gladly i know how to fix it for me, but it's still shameful.
