To follow up on this thread as well, I wanted to confirm that a hosted channel not showing in a Twitch embed is not a bug. However, it is functionality for the team to consider adding at some point in the future. I will add a UserVoice entry on your behalf for this request and link it here, then you can upvote and subscribe to be notified when the team has made a decision on whether or not this is functionality they would like to provide in the Twitch embed experience. I had incidentally closed out the one Barry referenced above as it was asking how to do it, not if it could be a new feature. Please feel free to add more comments on the entry below.
