LOL i was told that onemesh will support between 2 routers years ago and now it's been 2 years still no clue of what's happened. I have both AX6000 and AX73 in the closet and switched over to ASUS routers with Aimesh which is way better. Pretty sad but it's a fact. 

Bought two routers for this purpose, seller won't be happy when I return them as used tomorrow. And I won't be happy for having to pay for a different solution. 

Too bad really, seemed like a great product until I found this out after trying to mesh for almost four hours. 

  @Arn.B 

i bought An ax50 and AX10 tot discover thé ax50 wont het the mesh update, so I bought An ax73 to replace thé ax50 and discovered you Cant mesh  between 2 routers.

I'm a network guy and provided tplink for a lot of residentials until now. Never ever will I buy or recommend a TP-Link product to anyone anymore

I gave up waiting for this feature : I switched to one Deco X50 3-set pack. Now, I have what I missed : the ethernet backhaul on all satellites (not only the main satellite) + the mesh feature in AP mode.

Ugh...Just bought a second AX11000 hoping that I would be able to do a OneMesh network and like many others have been fooled. This is so stupid that you can't do this. Guess I'll be bringing this one back to the store. :( .... I really wanted this to work and I don't understand why they wouldn't make this an option, it's a no brainer.

I also have 2 of OneMesh router AX73 & AX20 and bought them more then a year ago with the plan to link to make a OneMesh.

Here are 2 other threads also asking for the same thing

OneMesh b/w Routers?

Create a OneMesh™ network between two routers

Can we all just get a Yes or No answer to whether this feature will be implemented ??

There is also the need for having the option for a Ethernet Backhaul, both between 2 routers and between a router and Range Extender.

As this was part of my plan

Again there are many threads about is.

[Wi-Fi Routers] AP Mode supports Onemesh

[Range Extender] OneMesh Supports Ethernet Backhaul

Ethernet Backhaul of Range Extenders

Onemesh in Access Point Mode

It is looking like as others have, I will have to head over to Asus and use AiMesh..................

I can't believe it 

Great, wasn't noted anywhere in the spec shees other than both the AX20 and AX55 routers are onemesh compatible. Perhaps make the 'you can't use multiple Onemesh routers' more obvious?

Good thing I can return these. Back to Ubiquiti and Asus it is.
