Here is the image which shows if there is no video still "2x training" button appear, so I don't think it not glitch/hangup with the video providers. Its glitch/hangup/bug on Nordeus side:
In this image, first part is you clicking the "2x button" then on second part (second step) another window popup which allow you to click for video. If there are no video then it'll give you error msg as I marked at the bottom of the image. My point is there are video available or not still "2x button" appear not disappear. In my case, "2x button" totally disappear.
Thanks
