RBK50V - Alexa integration with other Amazon Echo devices

RBK50V Orbi Mesh WiFi System with Orbi Voice Smart Speaker & WiFi Satellite

The RBK50 Voice satelletie I purchased does not integrate with the rest of Amazon devices I own. 

1. Unable to control other Alexa Devices (Echo Dot, Echo Plus and a Studio) from the Orbi Voice Satellite. 

2. The Orbi Voice would take command and respond despite that is placed furthest.

3. Whilst setting up a multi-room to play music through all Alexa/Amazon devices, only three of it show up in the search list to be added to the the multi-room setup. the Orbi Voice isn't listed. Netgear confirmed that as of the moment, multiple AVS is not supported. 

All those three features detailed above are basic features of an Amazon Echo device and would expect them to be implemeted in the Orbi Voice satellite as well. It clearly isn't stated on the product's description page that it won't integrate with other Amazon devices, so in that sense I feel that I have been mis-sold here.

Can these features please be added to the next firmware release please?
