Although I use an iPhone X, I only use Google services (music, photos, mail, etc.). – no Apple services at all. I just installed VOX on my phone but it doesn’t see the music files I have downloaded locally to my device using the Google Play music app.
I’m assuming this is not yet possible. Any idea if this is in the works? If so, I’d need a real timeframe when this will be implemented (not just ‘soon’), otherwise I’ll have to move on to another platform/subscription.
