I just wanted to point out that if you choose Continuous Streaming for Facebook that it does not end when you hit the End Stream Button.
You need to go into the settings and open the FB dialog box and End the Stream there.

Just ended my show and went to watch and I was still live.
Re-launched vMix and went into the setting and yep I was still streaming.

Then I hit the button and the stream ended.

Thanks everyone for all the help, I am looking at you PTZOptics and Tom Sinclair
