Sign In Problem - Error 422

Just registered and tried to download Insider Lite to a Samsung Galaxy 8. I confirmed my email and I think I got through the registration process, but when I try to sign in to Inssider Technician I get an Error Message - Error Signing In 422
What does that Erro Message mean?
Is Inssider Technician what I am supposed to be signing in to?
Any assistance will be greatly appreciated.

Hi Lew! Unfortunately we do currently not have a supported version of inSSIDer for Android.
inSSIDer Technician is a custom app for ISP technicians and is not compatible.
