We use Google Hangouts on Air to host a live show every week and use the built in YouTube comment system so people can respond and ask questions live. We've been doing this since Hangouts on Air started 3 or so years ago - using that comment system.
These past few weeks the comment system has been disabled on our Hangouts on Air for no reason. I don't know what's going on. We've been doing this for years now so I haven't done anything different and I know all the steps to get it running.
Here's our scheduled HoA for next Saturday:
Go to the actual watch page and notice the comment box below says "Comments are disabled".
I assure you, the comments are enabled on my live stream settings. Something has changed internally on HoA or Google or YouTube that is now disallowing comments.
I've also tried "live chat" on the side, but it doesn't work either. Plus, I would rather have the comment box instead because the comments stay on the video after the stream so people can read it later.
