Hi! I understand that your Jabra Enhance Pro app is only showing the "PHON" setting, and your usual settings like Restaurant and Outdoor Music are missing. Let’s work through this together.

Could you please confirm if you have recently updated the Jabra Enhance Pro app or the firmware on your hearing aids? Sometimes missing preset settings can be due to needing to download or refresh device profiles or settings.

Here’s a step-by-step approach to try:

1. Restart Your Devices
- Turn off your Jabra Enhance Pro hearing aids and wait about 30 seconds before turning them back on.
- Close the app entirely on your ChromeOS device and reopen it.

2. Check Bluetooth Connections
- Ensure that only your Jabra hearing aids are connected via Bluetooth on your ChromeOS device. Disconnect any other Bluetooth devices temporarily.
- Re-pair your hearing aids if needed by removing them from Bluetooth settings and connecting again.

3. Download or Refresh Settings in the App
- Open the Jabra Enhance Pro app and check for an option to download or update hearing aid settings or presets. This process refreshes your presets like Restaurant, Outdoor Music, etc.
- If prompted, allow the app to update your device settings.

4. Close Background Apps
- Sometimes other apps running simultaneously can interfere. Close unnecessary background apps before using the Jabra Enhance Pro app.

If after these steps the other presets still do not appear and you only see "PHON," it may indicate a syncing or firmware issue that might need further intervention.

Could you try these steps and let me know what you observe? Also, are you using the latest version of the Jabra Enhance Pro app from the Chrome Web Store or Google Play (depending on your device compatibility)?

If needed, I can guide you on how to check your firmware version and update it too.

Are you satisfied with these initial steps?
