Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.
Since you changed your password, your devices aren't able to get into email because they are still using the old password. Delete the email app, go to the app store, and download the app again. This will allow you to enter your email address and new password, and your emails will return.
Good job on changing your password! That is the exact thing that needs to be done when you get hacked. It is a good idea to change the password ***** all of your accounts that are linked to your email as well. They can get into your Facebook, and other accounts that use the same password ***** got hacked.
Were you able to update the passwords on the devices?
