I had played R6 Siege for over a year on Xbox Series X without any major issue. I recently started playing on PS4 too (since Y7S3 started). Everything was fine, but the game crashes frequently after a game ends, just when the final kill happens and after the kill cam ends, and before the winning team animation starts.
I'm not sure if this is something that has to do with the issue, but when I go to R6 site, either on desktop or mobile browsers, I see my general stats but no stats at all about operators. And most of the trophies that are related to playing or winning rounds with pathfinder operators are not being unlocked. For example, there's a couple of trophies for playing 10 matches as one pathfinder operator (one for defense, one for offense), and none of them are being unlocked.
How can I see my progress towards the trophies if stats don't work? Could it be related to the game crashes, so data is not correct or synchronized somehow?
