Good day. First of all I couldn't add the Deco E4r model on the model part (Firmare version: 1.1.2 Build 20250226 Rel. 35508)

Anyways, my main question is about the allow list mode that the deco X60 have. 

The main deco we are using is the X60 with other three deco E4r connected on it. The allow list mode sometimes works and visible but sometimes,  the option is unavailable. I know this is due to the different version or build but why does it sometimes allow it, sometimes not?

Here's the set up:

Main deco is X60

1 Deco E4r is comnected through LAN cable on the main deco

The other 2 Deco E4r is connected wirelessly.

I am wondering, if we connect all deco using LAN cable, will the allow list mode permanently work? Or still not, since it's different version after all

(MAIN DECO lan to 1ST DECO E4R)

(1ST DECO E4R lan to 2ND DECO E4R)

(2ND DECO E4R lan to 3RD DECO E4R)

Thank you.
