Hi there! I understand your new Tile isn’t helping you find your phone, which is definitely the key feature you wanted. Let’s work through this together to get it sorted out.

To start, could you tell me if when you double-press your Tile’s button, does your iPhone ring or make any sound at all? Also, is your iPhone nearby when you try this? Sometimes distance or Bluetooth issues can affect this functionality.

Meanwhile, here’s a step-by-step set of things we can check on your iPhone (iOS 18.7):

1. Check Tile App Permissions
- Open the Tile app and go to settings. Make sure the "Find Your Phone" feature is turned ON.
- Ensure Location Services are enabled for the Tile app (Settings > Privacy > Location Services). Set it to "Always" or "While Using" the app.
- Verify that Bluetooth is enabled on your iPhone (Settings > Bluetooth).

2. Background App Refresh
- Go to Settings > General > Background App Refresh, and make sure it is enabled for Tile. This allows the app to work in the background and maintain the connection to your Tile device.

3. Restart Everything
- Restart your iPhone and press the Tile button twice again to see if the phone rings.

4. Update the Tile App
- Check if the Tile app is updated to the latest version in the App Store.

5. Check Bluetooth Range and Interference
- Ensure that the Tile is within Bluetooth range (usually about 30 feet/10 meters) and away from devices that may cause interference.

If after these steps your Tile still can’t find your phone, please let me know which ones you tried and what happened at each step. I’m here to help you dig deeper if needed!

Are you able to try these and let me know what you find?
