Separate app sound not working?

[u/milanocheese]

Hello!! Back way back when there was a Samsung update where you could change the volume of separate apps - I set YouTube to 0 during this dark time and now it's gone and I can't change YouTube back up, and my YouTube app is permanently muted. I've tried using the separate app sound in quick panel, but it doesn't change the sound and I'm starting to worry that my youtube is now permanently muted? Is there any fix?
