Will I lose any data if I switch mail address associated with my Apple ID from @gmail.com to @icloud.com?
I am thinking about switching my Apple ID mail address from @gmail.com to @icloud.com. Basically just changing the mail associated with my Apple ID. If I do so by changing mail address in Reachable At: on iPhone will I lose any of my data(iCloud Drive data, contacts, photo, purchases, subscriptions)? Also my @icloud.com mail that I want to switch to is already located in “Reachable At:” section. So will I be even able to switch mail associated with Apple ID from @gmail.com to @icloud.com if that @icloud.com mail is already in my “Reachable At:” section but not the one which I log in to iCloud with?
