Ipad Air 2 and Tunein Pro app

Hello,

How do I get the lock screen image for a particular Internet radio station to display consistently when I am listening to a radio station using the Tunein Pro app? Sometimes the station info and time appear when the lock screen comes up; other times that information doesn't display and my homescreen displays. I would like to be able to view the station info and/or album art along with the time when I use the Tunein Pro app.

Thank you for your time.
