When you click Make Your Turn it doesn't process the move unless you hit refresh. You hit refresh after every move until you reach See Results. If you don't hit refresh then the battle never loads the results of the move. This is happening against all challengers, in normal battles and in battle quests.

Other people in the Battle Chat are having the same issue.

Seems like an issue with page reloads in general. Someone reported it here - Need to refresh the pages. :)
