On a mobile device, you can add or remove favorite stations by tapping the "Follow" button located in the top, right-hand corner of a station screen.
Once you tap "Follow," the "Follow" button changes to "Following" with a check mark next to it.
To remove as a favorite, tap the "Following" button to deselect it. The "Following" status will then return to "Follow."
Note: There is no limit to the number of stations you can follow.
