When I add my daughter's iPhone as a device in her child profile, the network generally freaks out.  A satellite Deco unit that is connected via Ethernet switches to Wireless connection, another satellite unit will blink its LED red, all devices will either drop on/off of the network or lose internet connection; the network becomes completely unstable and unusable.  When the device is removed from the child profile, the network immediately returns to normal functionality.

I have tried different devices on the child profile and the result is the same.

I have two children profiles created and the same occurs with both profiles.

I have the paid subscription for HomeShield.

All devices show as having up-to-date FW.

While the mesh network has worked flawlessly otherwise, not being able to use the parental control features is a major disappointment.
