Hi @alex
During the QA I was doing on upgrading to v7.1.7, I have noticed that email addresses do not get registered on the oppia server even if a user inputs the email in the registration steps.
On taking a closer look at the RegisterTask.java (oppia-mobile-android/RegisterTask.java at master · DigitalCampus/oppia-mobile-android · GitHub), I have noticed the email field is not being submitted to the server.
I am looking at the right file?
