OH @lupin_bebop here's something I ran into with my new laptop I think you'll have an answer for: My phone, the same one described above on iOS 12.5.4, is not recognized on the Music app on this new laptop. It was never a problem on my old one. This new laptop only has USB-C ports, as opposed to USB-A, and I don't have a lightning-USB-C cable yet so I got a USB-C-multi port (including USB-A) adapter that I use to plug my phone into my comp. I was wondering if Music doesn't recognized my phone because It's being run through USB-A to the USB-C converter to my laptop. But the thing with it is, my computer recognizes it enough to charge it.
