Deleting an Apple ID
I am signed in on my phone w my Apple ID, but my phone continuously asks me to sign in w an old Apple ID. I can’t find where to delete this I’d, as the I’d doesn’t seem to show up in my settings
Check the App Store and iTunes Store to see if there are any updates for apps/purchases. A request for an old Apple ID password is often caused by updates to apps/purchases that were made when using the old ID. One option is to delete the apps/purchases made by the old ID and download them using the new ID if desired.
If necessary, contact iTunes Support. Scroll to the bottom of the page in the 2nd link.
