I'm having trouble completing the firmware update or My purifier is stuck on "firmware updating" in the app?

The app notifies you every time the firmware in your device is being updated. Es ist unbedingt erforderlich, dass Sie den Luftreiniger bei Firmware -Updates nicht aus der Wand ziehen. During the update, you must keep your air purifier connected to the Wi-Fi to have the firmware update complete. The update should takes longer than 20 minutes. Please do not disconnect your unit during the update!

If the update takes longer than a few minutes:
• Ensure your air purifier is within the router range.
• Leave your air purifier ON and connected to the Wi-Fi. Ziehen Sie den Luftreiniger während des Update nicht aus.
• Limit the number of connected devices or network activity while the update is in progress.
What to do if the air purifier seems to be stuck in the “firmware update” for over 30 minutes?
• Turn off the Wi-Fi network.
• Attempt to connect to a different Wi-Fi network or personal mobile hotspot.
• Wenn Sie eine Verbindung zu einem neuen Wi-Fi-Netzwerk oder Hotspot herstellen, versucht das Gerät erneut zu aktualisieren.
