Problem

I created a profile on my computer. Now Duolingo wants me to create a profile on my iPad, but says the email address is already in use. Well, no kidding its mine.
Why isnt there a sign in option for someone who already has a profile, so I can study on my computer as well as sometimes on my iPad.
Im not able to move on to the next lesson without a way to sign in!!
