Hi! When logging in to the website, it used to send a verification code to my email. Now it only prompts the Dropbox app to authenticate log in, or via sms. It used to send to email but now I don't see it an an option. How to i add using email as login authentication option? Why does dropbox send send to the Dropbox app to. Authenticate log in? I don't remember changing it to that. Did this change at some point or did I change the setting without realizing it. Thanks!
