Spotify deleting downloaded music

[gloryatsea]

Just purchased a new Galaxy S9+, and it appears Spotify keeps deleting any music I download to my SD card. This is the same exact SD card I had in my LG V20 and I never had this problem. I had deleted everything before loading the SD card into my S9+, as well, so there shouldn't be any leftover files from before. I have since disconnected offline devices, reinstalled the Spotify app on my Android, and yet it still deleted all of my downloaded music in under 24 hours.

Is there a fix for this? This is an impressively glaring issue and I'm amazed this is even happening.
