My sign-in option for the app is currently set to “Public with email”, so anyone should be able to make an account and log in. However, when I try to log in on my phone with an account that is already in our Google docs spreadsheet it does not work and says “The email address doesn’t have access to this app. Please try another.” When trying to log in from a web browser, I can enter an email address and receive a PIN in my email, but when I enter that PIN, it does not work.
Has this happened with anyone else? How can I fix this?
