What is it that's taking you out of context? The logo at the top... It's probably the logo at the top. We'll de-link that, I think, ... at least for as long as there's a game going. Sorry, and thanks for raising this.
Btw, quickly force-quitting and then re-opening the app will probably get you back to your game in the meantime.
Someone please tell me how to recover a live game when I mistakenly touch something on my iPhone screen that takes me out of it. This keeps happening!!
