@TeamYouTube Your site has a new bug. I am watching a livestream and when I hit like, immediately after the 'added to likes' goes away, the like count visibly shifts back down one and the like I gave does not count. Please fix this.
Didn't try that, but it was happening to more than just me. The streamer's wife told me in the chat that she had the same problem with the likes. I did a google search and this bug has happened in years past as well.
