RBK50 Router + 3 RBS50 Satellites -- iOS app only showing Router (RBK50) and 2 Satellites

Successfully installed 1 x RBK50 (Router) and associated 3 x RBS50 (Satellites).  The system works and no complain about the performance so far.

Issue:  The IOS app home page will show that there are 3 satellites.  However, when I tap on the router to go into the topology screen, it will only show 1 x Router and 2 x Satellites -- the 3rd satellite does not show up.  Tried re-installing the IOS app but did not resolve this issue.

Remarks:  When I view via Orbilogin.net website, I can see all 3 satellites.
