For some reason  I’m no able to see or play my apple music files. I noticed that HighStereo version in Apple store is label 4.5, but once installed it is 4.3, am I using an old version?

### 1/5 — Can’t get mp3 files to generate

*2025-10-30, version 4.5*

Bought this to listen to some podcasts with some ambient effects in the bg. I’ve followed every step this thing has said to follow, I can’t even get a single file to open. Even went and hooked my phone to a laptop, went into apps, moved all the files directly to the app successfully, go to use the app and the pods are nowhere to be found. Pretty frustrating.

### 5/5 — 使い方が
