Login to your devices page here and remove your iOS device:
It may show up as "default". It's supposed to say what the deivce name is but sometimes it doesn't.
Then try downloading the songs again to see if they work in offline mode.
You can only have 3 devices with downloaded songs for offline use. Make sure you only have 3. If you have more than 3 then one of your devices will wipe the downloaded songs and cause it not to work.
Let me know how it goes.
I thought you had an iOS device because you posted this in the iOS section of the community.
What device are you using?
No problem. I went ahead and moved your post to the Android section.
I am going to tag @Daniel the Android expert to see if he can help.
