Add satellite to existing system

[rcbattin]

I have the Orbi system with the main router and 2 satellites.  I would like to add to more satellites to this existing system.  I have tried the Orbi app "add a satellite" and I have tried just clicking the sync on the router and each additional satellite separately.  It does not want to sync so what am I doing wrong.

What Orbi model do you have?

What satellite model are you trying to add to the system? 

What FW is on the system? Router and satellites have to be on same level version of FW.
