Encountering TVAPP-00209 on Xfinity Stream app on new Xumo Stream box (seems to work on all other devices)

Thanks for the tips, unfortunately I've tried that and more (including working with multiple agents via live chat and on the phone).  My latest troubleshooting attempt was to factory reset, but now I'm having trouble linking my account.  It shows my name, but it's not accepting my pin even though I'm 99% sure I have it correct (since it worked before and I don't think I've changed it).  In any case, I'm wondering if it's somehow related to the fact that I seem to have a 2nd "ghost" account.  By that I mean that sometimes when I login on the website it will make me select my account from 2 "different" accounts, though they are both identical copies of my address, though only the 2nd seems to work as expected when I select it.  Thoughts?

@user_fy1c8v Well that alone would frustrate me to have to deal with a ghost account. We can look into that as well. Can you tell me if the Xumo box was working previously? Is the only issue the Xfinity Stream app on it?

Yes, at one point I did have everything I tried (e.g. Netflix, Apple TV+, Hulu) working on the Xumo box EXCEPT the Xfinity Stream app.

@user_fy1c8v I'll need to take a look at your Xfinity ID and the account to see if that is the trouble. For this, I'll need to get your full name and address by way of a Direct Message, so I may review your account. I look forward to your message.
