New YT Material Design - YTC doesn't work

[VuYeK]

Hi, today YT on my account was updated to new material design (Firefox v52) but it completely doesn't work with YTC. There aren't any search bar or even YT logo. No new buttons from new design and what is most important: when you want to play any video - you get white blank screen and nothing more.

Just got the new Youtube Material Design thing today. It looks very mobile (clean, big buttons) and yes, Youtube Center (Developer Build) does not work - I only get a blank white screen when I want to watch a video.

I see there is a button to "Restore Classic Youtube," so I'm going to use that, but how long will it last?

For me the Firefox plugin even not working in the "classic" design Edit: i forgot to mention YTCenter settings also not working. it loads the youtube home page Edit2: it seems to be working downloaded from Mega

Using the Dev version and yeah, seems today they forced the update on everyone which has resulted in blank pages for videos. Before you could opt-out as I had done.

Hmmm I needed to opt-in to the new design and could opt out anytime via user menu. In case you really cannot opt out this way like I can, this bug is serious for YTC.

Found this a few hours ago and reverted along with an note to Youtube of features I use from YC that are missing. The one noticeable issue with reverting that I can see is the Player Size YC settings have no effect, the player remains the same size.
