I think it would be good if you let the community know of this like everytime you believe a country/color is complete, send out the message:Please DM me, you haven’t by any chance missed to update/confirm your address?
If you are expecting XXX color and are from YYY, please check your spam folder for the shipping confirmation, if not, contact me.
This way you don't end up later with the very patient people who haven't confirmed their address wondering where their case are.
