Notification Message Quest Wifi Test Deep Link

Today I've received on my Orbi app these five notifications: "Guest WiFi PN Guest WiFi Test deep link."  I've never rec'd this notification before and don't understand it.  There's also a box "Unable to Connect to Router."  My devices are connected to the Orbi router, so I don't know what is "unable to connect to router."  Also, the Guest WiFi setting is off; I don't recall ever using the guest wifi nor do I have a guest wifi password.  (This situation may be completely unrelated, but recently, I've notice that when I return home, my smart phone often does not automatically reconnect to the Orbi router.  It's staying connected to a random Xfinity connection (my Internet provider), even though the Orbi router is has a much better signal.  I have to manually connect the phone to the Orbi router.  Again, this is new problem.)  Thank you for your assistance in diagnosing this problem.  Gregg
