While owners of a newer LG or Vizio smart TV should have no trouble in accessing Peacock, those with a TV from other brands are likely to run into trouble. Arguably, the inclusion of Android TV support is quite important here as that includes a number of smart TVs from a variety of third-party brands, including Sony, Sharp, and Hisense. As a result, owners of a TV that is powered by Android TV should find they are able to download the Peacock app from the Google Play Store without too many issues.
I thought the same but you actually can sign under different devices after chatting with peacock customer service I was directed to reset password they sent the link through my email and I now stream through multiple non Roku devices. Reset ur password.
