Crossplay not working on Xbox for RedSec

Platform:
Xbox Series X

Game Mode Affected:
Battle Royale (RedSec)

Game Version:
1.0.389.47564

Description:
When playing Battlefield 6: RedSec on Xbox with crossplay enabled, the system consistently fails to match Xbox players with players on other platforms in the Battle Royale mode. I also have cross-network play allowed on my Xbox System. I know this cause crossplay functions correctly in the standard Multiplayer modes, but in Battle Royale, matches almost always consist exclusively of Xbox players. Multiple Xbox players in the same lobbies have confirmed the same issue. 

Please consider this a priority, as this is creating very long wait times for the RedSec and is deterring many Xbox players from playing this mode.
