I just finished doing a live stream on @YouTube, and I've got some suggestions for them. 1. Make it easier to share the stream. I hate that the YT stream is paused while I try to send to notification to Twitter. It should be seamless like @PeriscopeTV.
Thanks for reaching out! Our Help Center article has info on how you can share your live stream which may answer your question: https://goo.gl/bekYKs . Hope this helps.
