Not able to connect to Google Home Products when on NightHawk Mesh Wifi-6 (MK60)

Hello Netgear Community,

I have a NightHawk Mesh WiFi Router (MR60) + two of it's satellite (placed in different rooms)

What I have noticed that, I am not able to cast to Google Home devices like (Mini, Nest, Display etc) from either my Iphone, a Pixel or my MAC. The weird thing is that, if my phone is connected to a router or satellite not same as the one on which the google home mini is connected to, then the casting is successful. For example, say if my Google Home mini is connected to Satellite-1 then I am able to cast to it only when my phone is connected to Satellite-2 or the router. Tldr, I am not able to cast to a google devices when in the same room as the google device. 

This is true also when I ping other devices connected to the same router or satellite. I am able to ping other devices only on a different satellite or on the router.

I have verified that all devices are connected to the internet.

2.4GHz on Channel - 11

   5GHz on Channel - 161

(I have actually tried different combination of these channels, but not no effect.)

I have already tried restarting the firmware, factory reset, and the firmware is updated. Please don't suggest that. 

Please advice.

Thanks in advance.
