Please check which operational system is your phone using:
A) Android 9 Pie:
There is an issue with the way that this OS is using notifications, and therefore the Gogogate2 will not detect your phone. There is a new update that fixes that issue. Please make sure that you have the latest version of the App and then please connect your phone to the same network as the Gogogate2 and the message asking to update will appear.
In case of any issues with the update please visit this link.

About notifications in Gogogate2, please check if you meet this requirements:
