Hi there! I understand your Airbuds Widget's Lock Screen widget isn't working on your iPhone with iOS 18.7. Let's work through this together.

First, can you tell me a bit more about what's happening? For example:
- Does the widget not show up at all on the lock screen, or is it blank/unclickable?
- Have you tried restarting the phone or removing and re-adding the widget already?

Meanwhile, some common checks for this issue on iOS include:

1. Restart your iPhone: A quick reboot often resolves widget display glitches.
2. Check Widget Permissions:
- Go to Settings > Face ID & Passcode (or Touch ID & Passcode).
- Enter your passcode and scroll down to Allow Access When Locked.
- Make sure Today View and Search is toggled on to allow widgets on the lock screen.
3. Remove and Re-add the Widget:
- On the lock screen, long-press anywhere, tap Customize.
- Remove the Airbuds widget.
- Add it back again by tapping the plus (+) and selecting Airbuds.
4. Update or Reinstall the App:
- Check if there’s an app update in the App Store.
- If the problem continues, try deleting and reinstalling the Airbuds Widget app.
5. Check for Known iOS Widget Bugs:
- Some users report widgets going blank after updates and a reboot fixes this temporarily.
- There might be some refresh delays on iOS, so waiting a few minutes on the lock screen after re-adding the widget might help.

If you’ve already done some of these, please let me know which ones, and we can go deeper into settings or possible app-specific fixes.

Are you able to see any error messages or is it just not appearing? That will help me tailor the next steps.
