TVAPP-00148

When is this going to get resolved on being able to view the Xfinity stream App on Samsung TV. Xfinity Stream APP not working on my Samsung TV. Menu pops up but when I select channel getting error code : TVAPP-00148.  After spending over hour with tech and deleting app, reinstalling app, resetting password, resetting router still have same code.  Waiting on tech to get back to me.  The App works on my phone and Roku/firesticks
