Xbox players can't Matchmake with PC players

Hi, We are a group of 4 guys playing your game pretty often. I speak on behalf of all of us.>
3 of us are playing Battlefield 6 on PC, and 1 is on Xbox Series X. We've come to realize that, when in party together, all PC players are able to matchmake and enter the game except the Xbox player. This problem is intermittent and requires that we all leave the (just joined) game and relaunch the matchmaking process for him to access the game with the party. This issue also happens when finishing a game and switching to another map, all the PC players are following into the next game, except for the Xbox player.

We have tried to replicate this issue with a Playstation 5 and weren't able to replicate it yet.

Thank you for your time.
