pop up problem apple id verification
I recently upgraded to ios 10.0.2 on my iphone 6. I am now getting a continual popup (every 13 seconds) asking me for the password to an apple id that is connected to my previous apple id that I changed because that email account expired. I cannot change my apple id back to the old account even temporarily because it sends the verification code to that email address that no longer exists. This is very annoying and makes it difficult to use my phone.
iPhone 6s, iOS 10.0.2
