Streaming direct from xbox onto Twitch

I have tried to launch Gears Tactics on Twitch on the Xbox One - but it keeps saying “this game is not a broadcasting game” - is there a reason it is blocked

Might be one of the rare cases where devs care about giving people a spoilerfree expierence ( see Bioshock remaster, they blocked screenshots+clips as well). It’s more likely though that it’s just a bug or will be resolved once the “actual” launch happened.
