Yesterday I did a playtest session and apparently one of my friends who’s playing on xbox got rejected from joining the game (reason : round has already ended or smth like that) but it wasn’t even the last round.
He immediatly joined again and it worked but with the loading time he couldn’t make it in time and had to spectate us for the rest of the round (since I use Join in Progress: Spawn on Next Round setting 
Is there any setting I can check for it to be allowed or is it an already known issue ?
