I already asked on the AnswerHubanswers.unrealengine.com/questions/352302/unable-to-build-and-deploy-for-tvos.html, but since there was no response I’ll try it here 
I can’t get a build & deployment through for tvOS. On OSX I get a “No platform found error”. On Windows I’m actually able to build, but the deployment fails. Don’t know if it’s me that’s too dumb or there’s something wrong with Preview1 - any hints?
