How to remove old iCloud account from iPhone
My son had an iPhone SE 2020, since he upgraded it to iPhone 14, he gave his old iphone to his younger brother. Since the younger son was excited to have "his own iPhone" they did the swap by themselves and it looks that they did something wrong.
I don't know what did they mess, I know that for sure iPhone SE was wiped out, most likely remotly removed an account of my older son from it.
Problem is, that from time to time my younger son gets an popup to login to his older brother apple ID, sometimes he can't update apps as he is asked to login his brother account.
What should we do to remove this old apple account from iPhone SE?
I have an access to (by myself or via my son):
- iPhone 14, Apple ID and password of my older son
- iPhone SE, Apple ID and password of my younger son
All I need to know is how to fix it knowing all the passwords? If it is needed to wipe again iPhone SE, can I do the backup of it and older son account wont be back after backup restore?
Thank you in advance,
