I downloaded the songs my clicking make playlist availible offline. Green arrows appear everywhere. Once I disconnect all my internet functions it won't play. Also if I put the offline mode on before disconnecting the internet, the songs won't play.
What I've tried
-Deleting the cache
-Deleting all spotify related maps while phone was connected via USB
-With and without SD card inserted
-Motorola Moto G2
-64GB SD card (58GB free)
-More than 1GB free on my internal storage
-Spotify version: 18.104.22.1683
-Android version: 5.0.2
-System is up to date
As you can see all songs have a green arrow and when you play MOST OF THEM they won't start. Notice that I am in offline mode.
