I have used the app a couple seasons on an iPad. This season I had to migrate to a different iPad (Air 2). The OS version is 15.3.1. I am having an issue where songs I have added to my Apple Music library, and downloaded, just disappear. I go to select the song in the Walkout app and get a message that basically tells me I'm not online and need to be. I go to Apple Music and find that the song has disappeared from My Library. I re-add, re-download, disconnect Internet and everything is fine. This has happened enough that I'm going through my entire Walkout app before every game to test each song and re-download what I need to. Last game, I did this, closed the app to reset what had already been played and once the game started, we had songs disappear again. It's not the same songs every time.
