Hi there! I understand you're having trouble with the Scent Marketing app not finding your AromaTech diffuser. Let’s work through this together.

First, could you please confirm:
1. Is your diffuser plugged in and powered on?
2. Is Bluetooth enabled on your iPhone?
3. Are you close to the diffuser, ideally within a few feet?

These initial checks often resolve connection issues. If everything seems good from your side, we can try a few troubleshooting steps:

1. Restart the App: Close the Scent Marketing app completely and then reopen it.
2. Check Bluetooth Connectivity: On your iPhone, go to Settings > Bluetooth and ensure that it’s turned on. If your diffuser doesn't appear, try toggling Bluetooth off, waiting a few seconds, and then turning it back on.
3. Reboot the Diffuser: Unplug the diffuser, wait about 10 seconds, and plug it back in.
4. Location Settings: Ensure your phone’s location settings are enabled, as this might affect the Bluetooth connection.

After trying these steps, please let me know if your diffuser is still not found by the app. If it’s still an issue, we can explore more advanced troubleshooting or I can help you reach out for further assistance.
