No casual mode button

My mobile app has no casual play button only ranked. I can play a game fine on Europe server but in America only ranked game is available and there is no button at all

You must reach rank 25 to get it.

Is that some new rule?
Since when you can’t play casual and only ranked? I can’t get to 25 with the basic characters and cards so that’s not possible

Since rank 50 appeared.

If you cannot get rank 25 with basic cards, you have nothing to do in casual mode where opponents are much stronger than on rank 50-25.

im rank 25 and still dont have casual mode

Everything has changed. You must get out of junior league now.
