So i have an IOS 10 running ipad 4. ı wished to link an app to dropbox and i had to log in to do so. The only problem is i cannot log in as the placeholder 'Email' and 'Password' texts does not dissapear when i type in my email and the sign in button is always greyed out. log in with google or apple does not work either. When i click sign in, it flashes the whole log in box and nothing happens. Look, i understant you people no longer suppost old IOS devices when it comes to the app but what the hell is not being able to log in via BROWSER??
