My mum's work email address changed and we changed the email address associated with her apple ID. She had no end of tiny bugs pop up - especially in the first couple of weeks after the change.
Apple's systems in general don't seem to cope well with email addresses changing or being deleted. I think lots of software engineers use email addresses as if they're an immutable primary key. This just isn't the case.
