Yes, I’ve been having this issue for a couple weeks now. I also posted about it on the AppleViz forum. Usually YouTube iOS bugs don’t last this long. Hope they get it fixed soon

I am on iOS and I use voiceover and I used the YouTube app. As of late my share button likes to randomly disappear. On the video feed screen I don’t know what a technically called you can triple click the video before you click on it and you can get the share options that way but I’m not sure if you can like the video from there

I've been having this issue for the last 2 weeks or so. It doesn't seem to be fully consistent. It's all been there on a few videos, just the like button on a couple, and just the dislike button on one the other day.

I haven't found a way to get that part of the video player page to display again, but flicking up and tapping on a video outside of the player view still gives you options to share and add to playlist etc.

Sorry I can't be of more help than this. Hopefully it gets fixed soon.

It seems like they changed the order of UI Elements. It used to be Video, Channel Info, Buttons, Description. Now it's Video, Description, Buttons, Channel Info.

However, this seems to be different depending on if you're logged in or not. When I'm logged out, it seems closer to the the old UI.

These observations are based on using the YouTube website on a desktop internet browser.

Sometimes swiping around helps or sometime exiting the player screen. Sometimes full screen mode helps.
