Hi @cindy947
Welcome to community!
You should be able to use these steps to remove a station from your Roku Express
On your Roku, open Pandora* and go to My Station.
Using your remote, move your cursor over the name of the station you'd like to delete and press the star button on your remote. This should display the option to delete the station.
If you don't see this option, you may have an earlier model of Roku. You may need to delete those stations from our website or another device. (The changes will carry over.)
If you're still having trouble, let me know the name of the station.
Hope this helps!
