Name Change on icloud doesn't reflect change
I went about adding an alias to my icloud account after changing my last name following my marriage. My old email address was firstnameOldlastname@icloud.com, and my new alias that I used is firstname.newlastname@icloud.com. That's great, it shows the email address, however, the name listed with the email is still the old last name. I have gone into the settings on icloud.com and changed the name associated with it, and continue to have this issue. I've changed it on my phone, on my macbook, and at icloud.com, and all reflect the new last name. The only place it shows the old last name is when emails are sent.
Does anyone know why this might be happening, or how to fix it?
