Double pressing the button on the device is not starting a recording?

After your Frontier X3 has been restarted or rebooted, it needs to be connected to the app, and the first session needs to be started from the app rather than by double-pressing the button on
the device.

When you receive the device for the first time and connect it to the app, you should receive a firmware upgrade automatically. If you do not, perform the upgrade manually from the settings page in the app. After the upgrade the device reboots and reconnects to the app. Start your first session from the app; from then on, double pressing the button will start recordings normally without the app.
