Before the latest update: This achievement only required you to play an official event, then after the game finished your score would automatically post, as long as you met the point requirement for the season tokens (tab beside tournament to the right), but now it's unobtainable until Zen Studios can fix it. As you can see, it has not been popped since 12/5/23. I got the achievement before the update, but it will not pop on the Xbox ONE, which TA has that achievement discontinued on trueachievements for Xbox. I have messaged Zen Studios about this. Hopefully they will get this problem fixed soon. I'm pretty sure most all of the DLC achievements are also corrupt, possibly even the season achievement because I completed that today on the Xbox, it too did not pop.
