Nokia 8 Sirocco / iPod Touch 6th generation
Android 10 / IOS12.5.1
My Question or Issue
I have over 4000 songs (including just over 100 local files) in my library and they are locally downloaded onto my smartphone (Nokia 8 Sirocco). I also have a Macbook Air, but on this device my library isn't downloaded.
About two months ago, I noticed all my downloads were suddenly deleted from my Nokia, and since then, this has been happening about every 10 days. I have followed basic troubleshooting suggestions from the community such as reinstalling the app, making sure there are no cache limits set to the app... And to make sure this wasn't a problem with my phone, I also redownloaded everything onto my old iPod (which is the iPod Touch 6th generation mentioned above) but I have the same problem on this device.
Since redownloading over 4000 songs on an almost weekly basis while paying for a premium subscription is not really okay, some help on what I can do would be very much appreciated.
