The app is slow – iHeart: Radio, Podcasts, Music Review

The problem I have on my iPhone 10 Is that after I turn on the app I can’t change Any thing for about 30 seconds then when I turn on the channel I listen to I have to wait 30 seconds again then any changes I like to make I have to wait 30 seconds I was hoping that would improve after paying But still the same problem so I went back to the free version, I have deleted the app and then reinstalled it no change, does IHeartRadio not like iPhones ?
