I am trying to load peacock network on my Roku express but it says it is already installed but it is not listed on the home screen.
Did you verify if your Express model # is supported? (Settings/System/About)
Roku 2 (4210X model only)
Roku 3 & 4 (model 4200X or later)
Roku Streaming Stick (model 3600X or later)
Roku Express/Express+ (model 3900X or later)
Roku Premiere/Premiere+ (model 3920X or later)
Roku Ultra/Ultra LT (model 4640X or later)
Roku TV and Smart Soundbar (model 5000X or later)
If your Express/Express+ is a 3700/3710, you wont be able to install the Peacock app - you'll need to upgrade to a newer model.
