How do I remove Accessibility background sounds?
After installing iOS 15, I thought I'd give Background Sounds a try. After turning on Background Sounds in Audio/Visual prefs, I listened to Stream, Rain, Ocean, etc. While doing so, I saw the the sound files were being downloaded (and no way to stop that). After trying the sounds I decided that this option wasn't for me, and I turned it off. Now I have these sound files in memory somewhere and don't need/want them. How do I delete them? I rebooted the phone but they are still there. All I find with Google is how to use them, not how to remove them.
Thanks in advance for your advice.
iPhone SE, iOS 15
