iCloud password won't stop loading.
I had to reset my password to all my accounts, so I thought I would do the same to iCloud. When I went into the AppStore I noticed that my AppleID was from a long defunct email address, so I changed it to a current one. Easy enough. I also changed my AppleID password. Then I went onto my iPad and an iCloud sign in window appeared asking me to enter the AppleID password for my old email. I entered my new password, figuring since I got the verification email, it was all set. Nope. It won't accept the new password because iCloud still recognizes my old email. I've gone into iCloud.com to manage my ID and it shows the new and current email. I can't seem to get my devices to recognize my new iCloud ID, and the sign in box will not leave. It is blocking the operation of the iPad. I've heard that you can delete your iCloud account and start over. Is this recommended?
Ideas?
