This was probably working earlier.

I have a Samsung soundbar blocked using access control, on my router (Archer AX3200 v1.0 Firmware: 1.1.1 Build 20220120 rel.65572(5553)). This Samsung device was getting properly blocked on my network earlier before I added the OneMesh extender RE315 to my network. I could earlier verify that there were no DNS queries from the soundbar to my local DNS server (pi-hole). However after installig RE315, the soundbar has become a client to the extender (RE315) and is able to again spam my DNS server incessantly. In am unable to use/activate the RE315's access control to block it because under OneMesh mode, the access control / parental control etc settings are supposed to sync between the router and the extender, so UI does not allow me to touch RE315's access control toggle. I can see the client in the connected client list on RE315 but cannot do anything to block it. The client (as I earlier mentioned) is already blocked using the router blacklist. This seems broken.

Apologies if this has already been answered somewhere. Any help will be appreciated.
