Apple Store login ID is grayed out and cannot be changed
apple store login ID needs to be changed but grayed out. My iPhone 15 bought by my son who logged in with his ID then gave it to me and I logged in with mine. All my account info are correct except for apple store that shows his ID and it doesn't give me the possibility to change it with mine. When I bought my apple watch today now the problem is reflected also I'm there. Was online with help for an hour without a solution
