OnDemand Apps not working 12/4/19

Trying to access On Demand Apps Pandora and Prime Video and neither will open today.  Anyone else experiencing this issue?  I've Restarted and powercycled my TV Box with no resolution.  I can play Pandora thru the App on my LG TV fine using my Comcast internet connection, but NOT thru the TV Box app.  Was working when I went to bed last night, but not working this morning 7a ET.

UPDATE 8:30a:

When powering TV off/on when On Demand Apps had been selected (and failing to open), I get audio from the TV channel but a screen with error message:

                                      Oops.....

Unfortunately this feature is not working.

Our engineers are hard at work to resolve this problem.

Can a Comcast agent verify this?
