hello. please help me

i have a mesh made of 3 deco x20's and a deco m3 set

i want to replace the m3 with something more modern so i can use connection preference on my devices.

while there is beta firmware out for the deco m4 that makes it work with connection preference, it hasn't been updated in a while as tplink seems to be ditching their wifi 5 equipment.

which is the cheapest wifi 6 enabled deco that also supports connection preference for client devices? i think it would be the deco x10 but i am not a lble to find any info on it.

also can someone please fix the issue that when making a post on mobile,  the keyboard doesnt pop up when you click on the model section making it so that you cannot pos from qny browser on iphone?
