Thing is, this all worked on the first day and I even got a confirmation email.
I tried it again with all browser add-ons (i.e. adblock) off, third-party cookies enabled.
So all the analytics on the registration page: Adobe, demdex.net, google, doubleclick etc. happening, it still goes to "Whoops something went wrong".
Tried another PC and version of Firefox, the registration page jumped immediately to "Whoops, looks like something went wrong." Javascript is such rocket science, and generating a useful error message would be great.
It not a good day, for the stock markets or coronavirus so I leave this alone as I have low patience.
I don't even know if Keysight is monetizing my private data, entering a phone number etc. to be shared with third-parties is not in a spirit of respect.
Fluke/Fortive has these contests done in a superior manner and profiles a person much better. Maybe another year Keysight can fix/improve it.
