xfinity stream 4k

I am unable to retrieve any DVR recordings on the Xfinity Stream App.  My new X1 box (4K) shows the recordings are there and the box will let me play them back.  

Now I try to play back the recordings on a different devices in my home, same network.  Will not work.  Only live TV can be watched.

The App on my computer reports:

"Unable to Retrieve Scheduled Recordings

There was a problem retrieving your scheduled recordings. Please try again. Apologies for any inconvenience."

The App on my LG TV reports:

"Sorry, we're having some trouble.  Please check back later.

(Error: TVAPP-00815)

I've had this problem for months.  It was fixed when my original X1 was replaced a different, larger X1 box that apparently had an internal hard drive.  Then the problem reappeared when I swapped that box out for a 4K box which I believe uses cloud storage.

Apparently Xfinity Stream App is unable to pull DVR content off the Internet, even with the same Internet connection from all the devices:  TV with the X1 box, second TV with the App, and computer with the App.

I have tried system refresh and sync, nothing seems to help.
