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 tap on the "This device" button and select "Not installed", then tap on "Scanner Radio Pro", and then tap on the Install button.
