My Whisper Flex (Ultimate) will not connect to the app. What can I do?

Whisper Flex (Ultimate) has two different pairing modes. To pair the device with the Duux app, it is important that the Wi-Fi icon flashes rapidly. If you press and hold the control dial for 5 seconds, your device will switch to the correct pairing mode and the icon will start flashing rapidly.

If you are sure that the Wi-Fi icon is flashing rapidly, you can go through the app pairing process again. On this page (page: how do I connect my Whisper Flex to the Duux app?) we show you how to do that.
