Is the app not working for anyone else?

App was working fine for me the other day when I downloaded it, but for the past three days I haven't been able to log in. Each time I enter my login information, the page loads for a split second before going back to the "enter your email to sign in" page. I've tried making sure the app is up-to-date, reinstalling, and selecting the park before attempting to log in, but I still keep getting stuck in an endless loop of having to log in.
