Keith, the "create account" link on iOS is in the "Account" dialog, beneath the "sign in" button. iOS is the only app that has an Account dialog, because iOS has a few other configuration options to handle different store scenarios not present on the other platforms. Are you not seeing it in that location?
Regarding the string, the difference is unintentional. Username is the more generic term and one we use across all mobile device viewers. We chose username because some authentication providers don't require an email address, so labeling it "email address" may be inaccurate.
Ah, I see. Thanks for the context. The differences between iOS and the other platforms was based on what I had said before, but your scenario obviously wasn't considered. I've shared details with the dev team on this.
Nathan, I understand that the "create account" link on iOS is in the "Account" dialog in the hamburger menu. However, here's the problem: Imagine a new user is in the app, and they do not have an account and are not signed in. They encounter some entitled content with the lock.
When they tap "sign in" from one of these screens, all they see is the log-in screen below on iOS devices.
In this case, they have no idea how to create an account. They aren't going to know to go to the hamburger menu and tap on "account" to find it.
Both the Android and Web Viewer sign in screens have the "Create an account" link. The iOS sign in screen needs to have this as well!
