Password not being accepted for Apple TV+
I am going round in circles. Please can anyone help!?. I have used the same account/email address for decades on Apple products and services. When I try to redeem an offer through Sky for a trial of Apple TV+ my password (taken from my iPhone 12) is not accepted. I have tried copying and pasting as well as typing it in to no avail. Does anyone have any ideas please?
iPhone 12, iOS 16
