Can not get Netgear Nighthawk iOS App to Work on new iPad

I have been using the Netgear Nighthawk app successfully on both my iPhone and iPad for almost a year.  This week I purchased a new iPad Air (2019 - 10.5 inch).  When the Nighthawk app opens on the iPad, it has a prefilled user ID of Admin.  I have my own ID and my own password (previously set). The start up screen does not allow me to enter my ID & PW.  I delete the app from my iPad, and reinstall.  Now I can add the user ID & PW.  When I run the app it does not allow me to connect to my router (model R7960P, Nighthawk X6S), and defaults back to a start up screen that has the default ID of Admin.  How can I get Nighthawk App (iOS) to work on my new iPad (iOS 13.5)?   Help.  TIA

Best Regards,
