Bug in Hearthstone

Hello Customer Service

When I start a Hearthstone game (rated), I get a message at the beginning that I can choose a free deck—all well and good, but the message keeps popping up and I can’t start any rounds. Since the message pops up, and I’ve already chosen one, I can’t do anything and have to restart the game, and then the circle starts again from the beginning. Please help me.

They are working on this bug.
