I paid for the Scanner Radio Pro app in the past, how do I reinstall it?

To reinstall the Scanner Radio Pro app, launch the Play Store app, then tap on the colored circle that's in the top-right corner of the screen, then select "Manage apps & devices", then tap on the "Manage" tab that's at the top of the screen, then change the "Installed" drop-down to "Not Installed", then select "Scanner Radio Pro", and then tap on the Install button.
