Xfinity Stream Beta App Not Working on Samsung Smart TVs

When I download the Xfinity Stream Beta App then follow the steps to authorize it from my phone. It show success on my phone. However, on my TVs I get error:TVAPP-00165. I’ve reset the smart hub, router, deleted the app and reinstalled it several times. I still get the same error code. I’ve read several post here and it seems this problem has been around for awhile. Has anyone been able to fix it?
