DVR recordings do not show desktop computer or mobile streaming app, but do on TV set top box/TV

I have spent an hour on each of the last two days with a "tech". Neither can solve the problem of DVR recordings nor showing up on stream apps (desktop computer or mobile). Both have said I will get a follow up call since they could not solve the problem. Yesterday, I did not get the call; we'll see if I get one today.

Further, after the gyrations the tech put me through, I cannot even sign on to my mobile streaming app (Samsung S20). I can only get there on my browser. (xfinity.com/stream).

I have the distinct feeling that the whole web infrastructure on Comcast is a just a patchwork and it is in chaos. Time to leave if they cannot get their act together.
