Normally, you would need to click on the three dots ( on YouTube’s Mobile Apps ) when you want to share a video or change the quality. Then, the video would be blurry and the options would appear on the video. However, now Google just changed the design of the options menu.
First of all, when you click on the three dots, a white card will appear on the bottom from where you can report the video, change the quality, open the captions or enable the CardBoard view.
This feature does not come with the update as it is a change made in YouTube’s server.
