I completed the first task and stopped playing to see what the next task would be. It says "the next task will be available in 1hr 26 minutes" but it has said this now for several hours. I know that the next task is likely to be win 10 battles but I don't want to keep playing until this is confirmed. Has anyone else had this issue?
