Hey hhaahhaa2006,
Thanks for reaching out and welcome to forums!
As it stands, cross-play feature is yet to be introduced into the game, however cross-progression is already live.
As soon as there will be further information regarding cross-play, details will be posted here, in our official forums, therefore keep an eye!
