If you cannot see any Wi-Fi networks listed in the OtO app:
1. Double check your app permissions. In order for OtO to function properly, both "Nearby devices permission" and "Location" - with "Precise location" enabled - must be allowed.
To change these settings, tap-hold on the app icon in your phone. This should give you the option to view App Settings > App permissions.
2. You must also have Location Services enabled on your phone.
If you are using an iPhone: Ensure your phone is ALSO connected to the Wi-fi you want OtO to connect with. If it is not connected, it will not show up in the list.
