I bought recently AX23 (EU) 1.20, I use it as satellite mode and connect it to my Vx1800v usign EasyMesh. The connectivity is ok as you can see from the following screenshot from my Vx1800V WebUI.

My First conern that I can't check or update my Sattelite device as it is nothing shown under Firmware page

Second concern, from Tether APP the Icon for my AX23 is generic as it is not shown it as AX23 Wireless router as you can see while my another Satellite device RE305 V4 it shown correctly:

3rd concern, As you know from Tether app, any device connected to my Vx1800v I can see the Up/Down rate which is live so I can know which device is downloading or uploading. If the device moved to another location and switched to my Satellite device AX23, the Up/Down rate still 0 Byte so it will b dummy to me who is consuming the bandwidh and as you know AX23 support this feature if it is the Main router.

Last bug, From Tether App any device connected to AX23 it shown is using 5GHZ band while the devices can be connected to 2.4GHZ band as my Kitchen TV:

Fridge is connected to 2.4GHZ as shown from WebUI while from Tether App you can see it connected 5GHZ which is not correct.

And you can see that the Upload/download is 0kbps all the time if the devices connected to it.

Finally, as you know we can't manage the satellite device from Web or Tether, we hope to add this feature as it will be helpfull.
