IOS 11 Problem – Calc-12E RPN Financial Review

I have an iPhone 8 Plus running IOS 11. If I’m listening to an stream of audio and/video, the stream stops 90% of the time when starting your app. If I pull down the control center the play/pause button needs to be pressed play to start the streaming again.
