I had no idea each device has a limit on how many icloud accounts can be created on it (I'm sure apple users know this, But as a lifelong samsung user this would never have entered my mind)
It's saying I can no longer create a new icloud on the phone, but I can sign in using an existing one.
Do I just put this in the ad when I sell it, then people already with an icloud account can use it, or do I contact apple before sale? Is there anything they can even do?
It happened because when I first got it I used it for work, after a few months I then signed out and made a new icloud to use as my personal one, then my son took it once my upgrade arrived but couldn't get used to it which used up all three.
I bought the phone new outright and have the receipt.
