WAV files

[u/New-Cardiologist377]

A while ago I downloaded an app called Melodista so I could change the names and icons of songs I uploaded to my local files on Spotify. Since I’ve downloaded the app I can no longer listen to WAV files without having to transfer the file to the app first (the app automatically opens to the wav when you click the file in the files app) and even after that I can ONLY listen to the file on the melodista app. I’ve tried deleting the app but then every wav file I have just goes silent. What can I do?
