iOS Orbi app with RBK50

Hello,

I have the RBK50 Orbi mesh system with 1 satellite. It really works well with all our devices via WiFi and wired. 

But one thing is a mystery to me. How can it be that the app on my iPad and iphone doesn't show all the connected devises? The ones I don't see work just fine but I cannot give them a name or can't block/unblock them.

My router has the latest firmware and the app is the most recent.
