Last week I got a X50-5G for my new 5G internet connection. Nothing special about this.

Today I got my 3-pack of XE75. All Decos are connected through Ethernet, everything is fine - but I cannot find "IOT Network" in the Deco-App.

There was also an issue updating the XE75s: I went several time through the update process in the app, but everytime I got a "new" firmware update. So I downloaded the firmware (https://www.tp-link.com/de/support/download/deco-xe75/v2/#Firmware) and updated it via the web interface. But after several reboots of all devices there is still no "IoT Network" in the "More" tab of the Deco app. I also deleted and reinstalled the app onto my phone.

Here is a screenshot of all my Decos:
