Pixel 5, same issue! It takes for the ever to load device music I want to be able to shuffle between all my songs and not just have to click on one set of songs or the other to be able to listen to all of them while driving or something. The ones that I bought work just fine but the ones I have personally downloaded to my phone take forever to load. Reports say that music on local storage either shows up very slowly (a couple of minutes or more) or doesn’t load at all. There has been a slew of complaints on the official YouTube Music forums regarding this. And now, there’s the issue where device files are showing up slow. Previously, there were widespread complaints of missing songs and features. Let’s just admit that Google’s transition from Google Play Music to YouTube Music hasn’t exactly been smooth for users.
