Recently, I have tried using my Spotify account offline/in airplane mode because I have been traveling and either am away from any WiFi or data connection, or just want to reduce my data usage. When I put my phone into Airplane mode, only about 5 or six of my songs out of about 1,000 are available to play. However, all of my 1,000 or so songs have the green arrow next to them, indicating that they are available offline, yet when I try to access them offline, they won't play. I'm not sure how to make it so those songs will download so that I can listen to them while on Airplane mode. If anyone has any idea why this is happening, I would greatly appreciate a solution! Thanks!
