How to eliminate an apparent old or incorrect Apple ID
I just purchased a new iPad. I have it pretty much mirroring my iPhone. Unfortunately, the apps will not update on the iPad because when I am asked to log into the Apple Store, my personal Gmail address is displayed versus my Apple ID (user@me.com) as on my iPhone. There is no option to change the id during my log in attempts to the correct Apple ID.
How do I eliminate the Apple Store thinking I am logging in using my gmail account vs my Apple ID?
