On multiple attempts on multiple devices on multiple browsers, the reCaptcha portion of the new account sign-up process (a co-worker is trying to join) fails.
The text says:
“Something went wrong while creating your account
The server returned an error: Gateway Rejected: avs”
(Italics are part of the displayed text)
Back to the previous step button goes back to practically the beginning of the sign-up process. Also the “I’m not a robot” click process works and puts up a checkbox properly.
