Thank you for reaching out to us @user_698fe0! We have a dedicated article for activating the Stream app on LG, Samsung, and Xumo Smart TVs here. Is your Samsung TV a model from 2018 to 2025?

We're having the same issue. Works on Roku TV (on another Samsung tv) but our main one keeps giving us the error message (Tvapp-0166). Xfinity Stream is the worst app ever!

@user_q2mmmm Have you rechecked your Samsung TV to see if you're still having trouble with the Xfinity Stream app?

pormd Thanks for your comment. Is this happening on a Samsung TV too or a different kind of device? What troubleshooting steps have you tried so far?

Yes, been having the same problem. Finally got to talk to a customer service rep (after hours of dealing with the worthless chat 'assistant'.) Immediately she confirmed that there is a known problem that has been elevated to a high-priority specifically with the streaming app on Samsung TV's. Hope to have it fixed within 24 hrs. Why they couldn't have made that info more available earlier, I don't know. Xfinity customer support is absolutely the worst. I will be looking into the alternatives for sure..

Getting the same error

Spent an hour on live chat and the agent didn’t know this was going on. The app is going through an update.

Tried earlier this AM, no dice. Customer Support is supposed to contact me when it is resolved. I'll believe it when it happens. In the mean time, I'm doing a free trial of DTV.

The clock is ticking...

I’ve have the same problem .  Unplugged the TV overnight and code is still not working.

I spent the best part of 7 hours over 2 days with Xfinity as well as 2 hours with Samsung support. Nothing they suggested worked.

No matter what we did the app would took me to a login page. Would attempt to login by going to the internet or by scanning a QR code.

Both methods would tell me that everything was  Ok and that the app would take me to the xfinity programming. Unfortunately, I would immediately get a message telling me:

Something went wrong. Try again later and error TVAPP-00166.

The only APP that does not work properly on Samsung is the Xfinity App. It may be on purpose to force the usage of a box.

All other apps worked well. You have only two solutions that work. 1) Buy a Roku stick and access the xfinity app from there. 2) this one worked but it causes you to repeat the setup;  perform

a factory reset or a light reset and reinstall the xfinity app.

I did a light reset and had to setup from scratch to my network, reinstall Xfinity stream and any other app not already in Samsung (like Xumo).

It is an inconvenience but it works.

It should be fixed now. I was able to get mine working yesterday evening. About an hour later I got a robo-call from Xfinity telling me it was resolved.

Hello, user_uj1i8z! If you have not already can you check for updates on your Samsung TV, and also for the Stream app, and let me know if an update was available and if it helped?
