Hi and welcome back to the glorious wonders of GTP hahaha, yeah its not like how it used to be but as with all good things come to an end I guess?
In any case, regarding your current issue with Twitch streaming with TitanFall this was posted 3 days ago and Microsoft are aware of the issue:

However from what I have been reading there seems to be a temporary fix which may or may not work and that is to uninstall the app, delete the app data then reinstall the app.
Hope the above helps and happy gaming!
