All my rokus are on same account and should mirror all channels on each device. Why is a channel not showing up on one of my devices and I cannot add it when I search? It’s peacock tv
If that particular Roku device isn't supported by a channel, in this case Peacock, it won't install on that device. What model is it not appearing on? Model number please, not just its name. Roku has a bad habit of reusing names on different devices.
The NBC Peacock app for Roku was written by NBC to be compatible with the following Roku models (Check your model number via Settings > System > About):
