Bear in mind it may take a while for it to actually show up, I assume it will take until the match you just quit has ended. But it does work because I did it this month. (I did it purely because getting a rank was the only way to find out how many players were in ranked team adventure on the leaderboard, which it doesn’t tell you unless you yourself have qualified.)
Good job getting to 4850 Skajdrovski 
. 29th ranked in FFA 
.
Very nice, well done.
