Same Apple ID account, changed Apple ID
I have changed the Apple ID username associated with my account. it is the same account, same billing information and everything, i just changed the login user name. I am signed in on my iPad and iPhone with the new, corrected account ID. but when i try and update apps on either device it shows my old Apple ID, and will not update the apps. I would just delete and re-install the apps, but i have paid for most of them and do not want to pay for them again. is there anything that i can do?
