Have now several times experienced downloaded music is getting deleted.
In offline mode it starts with the login screen coming up (why ???)
After switching to online mode and logging in I check storage - it has changed from sd card to local.
Music is still on the sd card as I can see 51 GB available.
Try to open playlist of downloaded music - lists are there but no longer downloaded.
Check storage again - now 58GB free, so 7 GB has been deleted in the few minutes that took.
Now downloading again - again....
Please fix this issue.
