I'm sorry for the late reply. not sure what went wrong. I unlocked the platinum trophee a year ago so I'm not sure what exactly I did. If you haven't already → you'd better reach out to Ubisoft Support (and select your language of choice) if it still isn't unlocked.
Hi my friend. The season is finish. I already see the resolts but the tropihe still not apparence. Whats going on ? Its bug
