Access to Google Play music

Cannot access any of my music to play within the app. All my music is in Google Play 10,000 tracks and although they’re visible, they’re greyed out.

From reading on here (after my purchase, and excited to pick up where I left from iOS) I see it’s not possible. This is frankly ridiculous. You need to fix it, without it’s basically useless for anyone unless they’re going to download the music to a USB and them upload again, which is not going to happen every time I buy music let alone with all my existing music (presumably to take up double the space).

Madness and very very disappointing.
