yes, from the beginning of the season.
If you have a game (probably from another server) and you cannot see the "support" mask, then you go in a nearby time game of a friend who is in your server (an old one), go to his game, hit the support button and then you go back to the game of a friend and now you can see the "support" mask. Most of the times it's working (but you must have a game of your server available at that time).
Sometimes, you cannot see that the game is starting. Then, you must refresh the page.
