I can't see my cards on iPhone 12, they are cut off

I usually play Hearthstone on my desktop. I recently downloaded it on my iPhone 12 and when I open up the game, the bottom of the screen seems to be cut off so I cannot see enough of my cards to be able to play the game. I looked at settings to adjust the resolution, but there was no display settings to adjust. Can you tell me how to fix this problem? Thank you.

Tap and hold the card you want to see with your finger and it should bring that card up in the center of your screen as fully visible.
