Account not appearing in Duo app after clicking on email activation link or "take me to Duo Mobile" link. 

After clicking on the email activation link or the "take me to Duo Mobile" link and approving the popup to open Duo Mobile, you may be brought back to the "Welcome to Duo Mobile" or "Add your account" screen. Completely close or restart the Duo Mobile app and after reopening, you should see the Oregon State University account. Please note, simply exiting the app will not work. If you're not sure how to close out of the app completely, restarting your phone should also resolve this issue.
