Nighthawk AC1900 Not Connecting to App

[alex33x]

When I try to use the Nighthawk App it tells me I have to update my Firmware, but when I log into the Genie or my RouterSettings there is no place to update the firmware. When I go into ADVANCED > Administration There is no settings nor Administration.

   Trust no one, especially not a Netgear-supplied app.  Forget the app,
and use a web browser.

   You can't change the C7000[vX] firmware.
