I queued on mobile for sw solos at the same time as my kbm friend and got into the same game not in a party with 280 players on solos according to the statue in the sw hub. We tried 10 minutes later (the player count never dipped below 250) and we still got into the same game. PBMM isn’t working below 300 players still even though they changed it to 200.
IDK if this is true for any other gamemode, I only tested on sw solos.
