A. 1. Ensure Location Services are enabled for the GHIN app. Go to Settings > Privacy > Location Services, and make sure it’s turned on for GHIN. 2. Check if your iPhone has a clear view of the sky when using GPS. Tall buildings or dense trees can interfere with GPS signals. 3. Restart the Location Services by toggling it off and on in the same Location Services menu.

B. 4. Reset network settings by going to Settings > General > Reset > Reset Network Settings. This will reset Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.
