I can't Stream on My Twitch Account!

I have already Migrated my account to Mojang but when I hit F6 in Minecraft is says I have to Migrate my account to start streaming. And when I click "Start Stream" on OBS it starts but all you can see on my Twitch is just black but you hear sound.

It should say "Yes and No" if I hit F6 in Minecraft but it says "Cancel and Migrate Account".

I think this is a bug, I have done everything I need to do to stream but it doesn't work anyway. WHY!?

What do I do? Please Help Me <3
