Public radio problem

I am running the public radio player app on an iPhone 6+ under iOS 10. The app play the streams just fine on your iOS 9 but after I upgraded I can no longer get the app to play the streams or the Podcasts. The app indicates that something is loading or buffering but that's as far as it gets which indicates to me that there is probably some type of network connection problem. I have rebooted the phone several times and I uninstalled and reinstalled the app and nothing changes. Does anyone have any suggestions or comments about the situation? Thank you!
