Moving into hotfix

1. Open settings
2. If logged in, log out
3. Tap Log in
4. Tap Join Wikipedia
5. Tap Next
6. Verify that you are presented with a captcha
7. Enter the wrong text for the captcha
8. Verify that a new captcha is presented
9. Enter the correct text for the captcha
10. Verify that the new account is created and you are logged in

I tested this on my home Wifi with 5.0.6. After failing the first captcha:

• I saw an "Operation could not be completed (WMF 7)" error message
• Quickly replaced by the captcha required message
• Captcha reloaded as expected
• Enter the correct text
• See the "Operation could not be completed (WMF 7)" message
• See the Account created success message
• Am logged in and can edit with my user name as expected

So I am able to create and log into an account, but am seeing an unexpected error message (tried to screenshot but it is replaced too quickly by other messages).

I will try again on office Wifi later today.

Ok - that is odd…

@JMinor could you connect with Charles next time you do this? Would like to see the packages so we know what is getting returned to you.

Will do.

I'm testing on iOS 9.3.1 and Wikipedia 5.0.6 (906.1). I was provided with a new captcha when entering it wrongly (steps 7 and 8) and entering the correct captcha created the account (steps 9 and 10) so this is fixed.

From the office Wifi and AT&T LTE I get no errors and am able to create account without issue after captcha fail. I'll retest at home and see if the errors persist and attach session logs. If I don't see any issues at home I'm gonna assume this is a transient or server-side message we can ignore, and resolve until we can reliably repro.
