Same network throw APs

[GoNzCiD]

Hi, I have a RT-AC87U with merlin firmware and 2 RP-AC53 as AP, with the same ssid and channel set as auto in all 3 devices.

All end devices works fine, connection is quick accessing internet or Lan resources. But I have joined a pair of google home mini and I cannot see it in google assistant when my phone are joined to another ap.
It's needed to setup another special config to see all the lan as unique?


Thanks
