Lost my username and progress
A few weeks ago I was on Spanish Level 11. Recently, I changed the firmware on my smartphone and reinstalled Duolingo application. I logged into my account after the re-installation process and discovered that my username and all of my progress data disappeared. For some reason my current username is 2LhvOrfA I tried to change my username back to "Overslam" but the system says "The username is already taken". Is it possible to recover my account?
