Useless tool
States wrong format with the QR code.
Either QR code on the lock screen nor the QR code inside the lid works.
Garbage appQR code wrong format
Dometic tool scanning the QR code generated by Dometic CFX3 says the QR code is the wrong format. Only option is Try again so endless loop.Not in English
I was told to download this app from Dometic support but the app is in Chinese or Japanese. Gives a red exclamation point when I scan the QR code on my CFX3 75DZ.
