How do I make this birdy share work please?


I Love YTtalk
I've gone into creator and edit on one of my videos that i uploaded last week. I want to press the box that shares my video to my twitter page but it is un-selectable. :( I have already gone into youtube settings and linked my twitter account just today. But doesn't work. Is it for something else?Screen Shot 2017-11-07 at 14.20.37.png
hi thanks zhkopec he worked when i uploaded new content today. Ill go figure out how to put on about me page as well like you suggest.
I think it only works while you are uploading the video. I don't think you can check the box on a video that is already uploaded.
