I have been having an issue the last couple months where (seeming randomly), my downloaded Spotify library is moving from my SD card to local storage.  I have a farily large library, and this has completely blown away all my available local storage.

I've tried deleting the app data/cache, uninstalling the app, and manually removing the files twice now, but this keeps happening.

The bottom line is that the Spotify App now is making it difficult to use my phone at all.  Any ideas on how to resolve this?

I'm running Android Pie (but I had the same problem on the previous version of Android), on a Galaxy S9+

Thanks.
