Netgear Armor notice recommending I delete or reinstall Orbi app(?)

Over the past few days, my Orbi app notified me several times that it blocked access my NAS by suspicious devices.  On my phone this morning, I got a never-before-seen notice (apparently from Armor) saying "Phishing link found in notification" and recommding that I delete or reinstall Orbi app.  Next to the Orbi icon is a MAC address that is not mine but is similar to one that the Orbi app said it had earlier blocked.

I am not certain what is actually going on or if I really have to worry about my Orbi (or Armor) app. Thanks for any suggestions.
