@Wingmannedbro As I understand it's more of a technical reason than because of the $3.
@cheatercheater00 Sorry, but around launch there was the following comment basically saying cross-progression isn't going to happen.
"Although cross-play is unavailable at launch, Respawn told Eurogamer it "plans to allow players to play with their friends on other platforms". Cross-progress and cross-purchases, however, will never be possible in Apex Legends, "due to the way systems were set up early on" which "can't [be] reconciled after the fact".
