@BruceW​ which one is offered free as an xfinity tv subscriber??????????????

Xfinity customers get Peacock Premium for free. That is the full catalog, but with commercials (roughly 4-5min/hr). The non-Xfinity Peacock free has a limited catalog.

As noted, if you sign up properly through https://www.peacocktv.com/xfinity and create the account. You should be able to use that email/password on other devices. I use mine on Roku's and my phone. You can verify you can log in properly by going to https://www.peacocktv.com/ and logging in from the prompt at the upper-right. You can verify any account info, too.

I wouldn't be surprised if it happens just before NBC announces the first "Peacock exclusive" NFL regular season game.

@ThatDonGuy​ There are no "Peacock exclusive" NFL games.

Here's my problem. I have Xfinity internet and even have a flex box I use in my bedroom. Peacock Premium works on it at n/c. Got a new LG tv for the living room and when trying to log into Peacock it simply says "we couldn't find a match for this email and password. So I reset my password and logged in to my acct using new password on my computer. No problem. But when I try logging into Peacock on the app on my LG tv I get the same can't match email and password. I know I'm using the correct new password but the [Edited: "Language"] thing won't accept it. Are we not suppose to get Peacock on another device other than a Flex box? [Edited: "Language/Inflammatory"].

If you are having issues with the Peacock app on a third party device you would need to go to peacocktv.com/help for help with troubleshooting.
