Em, well there are 'rules' but nothing to the effect of not seeing it for a month. (More like, 1 time every 22 hrs, iircc)
If you click on the 'profile icon' then scroll down and look right above change your name, it should tell you what is needed.
For me it says "After your next multiplayer win", which seems to be "after you commit a MD turn or play a RT game from my experience.
I suspect opening a game, where it is not your turn can trigger it as well.
