when will apple ID users be able to change their profile pictures??

i’m not able to edit my name and profile picture in game due to me being signed with apple ID, can that be changed ?? why are apple ID users not allowed to change their profile picture

but i already crated a king account, it starts from level 1, i am currently using my apple ID and i’m on level 785, how can i merge my apple ID account with king ? not create a new king account, but merge them.
