It finally showed up in my app. Looks cool so far. My only complaint so far is there's no "save" function from the mix. You have to add the songs to a playlist and save to make it available offline. I can't use wifi at work for streaming so this may be a more "at home" feature.
I check the discover weekly playlist every Monday before and move the good songs into a "Discovered in Previous Weeks" playlist. It's pretty nice for remembering the artists I've discovered through it.
I've tried doing this but it still isn't popping up. Is this just an android/ios thing? I'm on desktop.
