iCloud+ Custom Email Domain: Email Address Not Available
Hello,
After successfully creating a custom email domain and setting up my own custom email address, I created another email address for a family member from my personal iCloud account.
I tried to add this account to my family member's iPhone and got the message: "This email address is not available. Please try again with a different address."
I then deleted the email address I created for my family member from my iCloud account, with the intention of making it available again for my family member to use.
However, when I try to set the email address up on my family member's iPhone, I still receive the same message.
From what I've been able to find online, it seems like I may have to wait some amount of time for the email address to become available again, but I'm not sure if this is correct.
How can I make this email address available again for my family member to use?
