I have to be on wifi to create a genius playlist?
i have different playlists on each of my devices. Today I tried to create a genius playlist from a song and first my iPhone froze up, then after closing the music app all of my playlist I had in my phone disappeared and all of my playlista from other devices loaded, then I got a message to connect to wifi to create a playlist. It then created a playlist, but after I turned off wifi the playlist disappeared. Tried it all again, only this time I got a message that rhere were not any songs that matched the song that I wanted to match.
iPhone 6, iOS 8.2
