I can't screen record Apple Music with audio
I'm an Iphone 6s+ user and my phone is at iOS 15.1. I purchased my Apple Music and been using it for half a year. But whenever I try to screen record Apple Music with the song audio on, there would be no audio recorded. No I'm not talking about my voice or background sound, it's all about the song playing on Apple Music. It just goes numb.
So how do I fix this problem? Sorry for my broken English.
