iCloud+ Custom domain name change problem when Apple ID already uses that same domain name?
What if my current Apple ID --- IS an email ALREADY using that domain, but presently configured elsewhere. I will need to reconfigure that domain's settings for use with Custom domain name iCloud+, so must I temporarily change my apple ID to be able to receive any confirmation or authentication emails during the transition? ex. Apple ID is hosted at google. I want to use grate.com as custom domain but now, instead of at google, at apple icloud+. So when I change the domain name settings to point at iCloud+, will there be a problem? Same for family user 2 or family user 3?
