Nighthawk iPhone Wifi app not working after update

[PHS62]

Hi, I'm new here.
I updated the Nighthawk WiFi app on my iPhone Xs MAX today. When I started the app, I got a window saying that I needed to Sign into Existing account or Create a new account. I have an account, so I selected Sign into... but nothing happened? Normally it should pop up a sign in Field or window, but nothing came up. Any of you had this abnormal function in this new version. The app version is 2.6.7.0

I'm having the same issue.  Had internet problems today, and that was a nightmare.  When I tried to see my devices thru the app, I got the same response, as if I had no router connected. Went ahead and power cycled the router, and all my devices were connected once more.  I was able to connect to the router with the desktop portal, but not the app.  Then I saw it was updated yesterday for me.
