And successfully used the passport scanning feature?
I've tried every which way and it doesn't seem to want to read the old-style (non-biometric) passport. It keeps giving an error during the "up-to-5-minute" upload process.
Yup, my spouse has an old-style passport. Worked perfectly with his old iPhone 5 when we traveled a couple of months ago.
Probably just a temporary server glitch in your case. Never any fun to hear, but better than a widespread problem.
