I have an apple ID to get into my "Apple Account" but my e-mail and ID for use in the APP store on my I-phone doesn't work and I don't know how to change it.
I have an apple ID to get into my "Apple Account" but my e-mail and ID for use in the APP store on my I-phone doesn't work and I don't know how to change it. The passwords I show in my records are incorrect. Is this something I can figure out on line or do I need to go to an Apple store or are Best Buy personnel able to help me?
iPhone 8, iOS 12
