@YouTube The "Watch Later" button on the top right of video thumbnails has stopped working for me. Any time I click on it it goes straight to the video instead of adding it to my watch later list. I've tried it on multiple computers too, but it's the same.
That's odd. To help the right team better investigate, can you send a feedback report from the device/account having the issue: https://goo.gl/WdI0BK ? You may not receive an individual response but the details will help us identify and fix any issues, thanks.
