Unable to connect my Dreame H14 Pro to the Dreamehome app

Hi,
Please try the following troubleshooting:

1. The Wi-Fi password is incorrect. Please confirm it's correct.
2. The device doesn't support 5GHz networks. Please confirm that the Wi-Fi is set to 2.4GHz. If not, you can try connecting to the app using the hotspot.
3. The Wi-Fi signal is weak. Please move the device to a location with a stronger Wi-Fi signal.
4. The app may not be configured yet. Please exit the app and try connecting again.
5. If scanning the QR code doesn't connect successfully, you can try manually adding a device to the network by clicking Add device/Add H series in the upper right corner.
6. Simultaneously press and hold the Voice button and the Clean button for 3 seconds until you hear the factory reset message and try again.
7. If the connection still fails, try turning Airplane mode on and off, then try connecting to the app again.

If the issue remains unresolved after completing the above steps, please contact support.na@dreame.tech for further investigation and assistance.
Also, please kindly provide a video of the problem to help with diagnosis.
