Ever since the most recent update, it has been SO HARD to play cards. And idk why, but this is the worst when the battle first started and I'm trying to play a land on my first 2 turns. Actually it may be a land card specific problem.
Anyways, I submitted a capture log. When the game refused to let me play a land card, I started furiously swiping up non stop. And it still want playing a land card. Then, somehow I dragged a land card onto the middle of the map, and it stayed there floating, highlighted in yellow after I let go of the card. Then trying to swipe the card to play it, I managed to drag the land card all the way to the bottom right of the map, where again it floated, highlighted in yellow after I let go.
