Expand RBR50 system with RBS350?

[Jootje]

Hello, I have an ORBI RBR50 system with 1 satelite. I want to expand this and bought an RBS350 but I can't get this to work. While adding in the app, the new satellite is not found. Can someone help me with this?

Thank you very much for the help.

Kind regards, jootje
