Hi there,
I have a "Dropbox Save & Restore" feature in my app, Fudget (www.fudget.com).
When the user enables this feature, I popup the Dropbox Auth Page.
And when the user starts typing an email address, the Email & Password fields disappear, so the user cannot login.
The fields seem to disappear as soon as you've typed in a string that would match as an email address (e.g. test@test.co)
You can see the problem in this video: https://www.dropbox.com/s/g7hcrz1pi1yufqw/Dropbox%20auth%20page%20-%20email%20%26%20password%20fields%20disappear.mov?dl=0
Note: this was working fine for several years, until the last few days. Now I am inundated with emails from users about this.
Thanks,
Danny
