Problem exist after disabling anti-tracking and add blocker feature. Before sign-in for synchronization work fine. After sign-in I get a trouble: after clicking on "Watch later" get blank window on a moment, and no adding to the Watch later list. If sign-off problem exist. Same problem in Firefox, but in Chrome and Edge work fine. Checked on several PCs. Very unpleasant problem for every day feature.

YouTube "Watch later" option not workingOpera for Windows
"Watch later" button not working on YouTube videos integrated in third party sites only in Opera. Try on dozen versions of Opera with same result. "Watch later" option (Clock icon in high right corner of video) work correctly on YouTube site.
