Daughter's Apple Watch locked to previous Apple Account
She changed her Apple I.D. a while ago but the watch wants her to log in with the old Apple ID and she’s forgotten those login details. When I try to reset her password on my iPhone it says her account is either not supported or is wrong. Nothing allows us to sort it, whatever we try
