My email address for Tumblr has been deleted (I signed up with a different email that’s not my main one) Due to the inactivity on that account it’s been deleted. So, now I can’t login on the desktop (or anywhere else) apart from this app that was signed in before the password update bullshit.
Does anyone know how I can change the email address either through this app or any other way..?
I’ve contacted Tumblr but they’ve said due to the privacy policy they can’t give out information, which is bullshit because I know the login email and password. I just need to change the registered email.

Help? Please…?
