Welcome to the Roku Community, @garybazo!
Thanks for reaching out. We'd be happy to be of assistance here and help you access all of the content available inside the Peacock TV app.
Firstly, do you have an existing subscription to this app? If so, do you know which type of subscription you purchased? If you see a lock icon on certain content on Peacock, it may indicate that a specific subscription is required to stream it.
For more details about streaming content inside the Peacock TV app on your Roku, we highly recommend connecting to their Support team for further assistance. You may reach them here: Peacock TV Support
We hope you find this information helpful.
Warm regards,
Carly
