Hey @ncksllvn @stephenBarrs. Just creating this issue so we have a place for any error messages we might need. If you identify any that don't already have standard messaging, feel free to drop in here and tag me and I'll write the messages. Thanks!

Hey @DanielleThierryUSDSVA this is the only error message we show currently. It's just a generic catch-all if the server doesn't indicate success after the user submits the form.

Once the captcha work continues though, we may have another error state to look for.
