I want to set up WiFi, but the App prompts me to set up Bluetooth. Why?

—The App will use Bluetooth to initiate connectivity between the App and the cooking device.

—There is no way of setting up WiFi without connecting via Bluetooth first. You only need Bluetooth for the initial setup. Then it is not needed.

—WiFi will take priority once set up, if WiFi is not present the controller will automatically swap to using Bluetooth.
