Hi there! I understand you've been having trouble with the autoplay feature in the BBC Sounds app on your iPhone. It's supposed to turn off when you toggle it, but it seems to be stuck on. Let's work through this together.

1. Double-check Autoplay Setting:
- Open the BBC Sounds app and go to 'My Sounds.'
- Tap on 'Settings' and ensure that the autoplay option is toggled off. Sometimes, toggling it off and then back on can help reset the feature.

2. Restart the App:
- Close the BBC Sounds app completely. You can do this by swiping up from the bottom of your screen (or double-tapping the Home button) to view your open apps, then swipe the BBC Sounds app off the screen. Restart the app to see if it respects the autoplay setting.

3. Device Restart:
- If the issue persists, try restarting your iPhone. Sometimes a simple reboot can clear out any temporary glitches that might affect app performance.

4. Update the App:
- Ensure that your BBC Sounds app is updated to the latest version. Go to the App Store, tap your profile icon at the top right, and check for any updates available for BBC Sounds.

5. Check for iPhone Software Update:
- Go to 'Settings' > 'General' > 'Software Update' on your iPhone, and see if there’s an available update. Keeping your device updated can resolve various compatibility issues with apps.

6. Reinstall the App:
- If none of the above steps work, uninstall the BBC Sounds app and then reinstall it from the App Store. This can often fix persistent bugs.

If you've tried all these steps and still have the autoplay issue, it could be something deeper within the app's settings or a potential bug. In that case, I'd recommend reaching out to BBC Sounds support directly at [email protected] for further assistance.
