student using app/site
Can students use the app and the site interchangeably? One of my students cannot use the same login information. The app says e-mail is already in use. Thanks!
Yes, the website and the app should be able to be used interchangeably.
Have you made sure that your student is trying to log in and not creating a new account? Sometimes when signing in on an app the first thing you are presented with is a "create new account" screen (or on the Apple app there are two options, the first of which is "get started" which is basically creating a new account) and you have to find the "already have an account?" prompt to get to the login screen.
That would be my suggestion as, other than not using the correct login information/password, the app should be able connect to the same account.
