Don't end the stream when you switch games
When you want to change a game with the twitch app or restart it the stream automatically ends and you have to restart. This is a problem for when your game freezes especially because you have to restart and you will lose your viewers
This is, sadly, not in the control of twitch. It is something you would need to take up with the console manufacturer. It most likely works that way so you don't accidentally show the world private info while in the consoles main menu which often shows your real name and sometimes email address, etc...
