yes, this can work as a trick.The second time, first I saw the action game my other friend, Jordi, I log in there and hit the support button.
When I went to watch the game with Celtic, this time the "support" mask was there and I hit it.
I don't know if hitting the previous "support", helped to see the mask.
If you can't watch a game of a friend (with white letters), and at that time you have a game of a friend from your server,
then you 'll go to your regular friend, press the support button
then you 'll go to the other friend which you couldn't support, and the support mask is appearing now
