Club Wars Glitch

I’m experiencing this glitch where after our most recent war, when I go in and it says “Ah, the spoils of war! Go ahead, open it!” and I go to open the chest, it won’t let me.

I’ve tried restarting the game and my device, but it still won’t allow me to open it. I’ve tried accessing Club Wars from both methods I know of, and neither work.

I was curious if anyone else was or has experienced this issue, and knows of a workaround, because now I can’t participate in any new/upcoming wars.
