I completed my current round of combat; however, I cannot move onto the next tier. This has happened in the past when I played on my ipad, but the issue resolved itself when I switched to my computer. Now, it is the same on all my devices. Has anyone encountered this issue before and successfully moved past the bug?

(P.S. I tried posting this before, but it ended up in the wrong place. My apologies.)
