I have two iCloud accounts. One has all my stuff on it (iA), the other one has my personal email address as the primary verified iCloud logon/email (iB). I'd like to move the email address on (iB) to my main account, (iA). I'm not fussed about merging the accounts, and I don't really care what email address ends up on (iB), but I'd like to de-associate my email address with (iB) and put it on (iA). It doesn't seem as simple to remove the primary email address from (iB) as it is to remove secondary email addresses; it seems to insist it's still verified with another iCloud account when I try to add it to (iA). Any suggestions?
