After the latest update, the game can not be played now.
Sending a chat message, entering the war zone, or entering GlobalHQ takes (if ever) even more than a minute.
I have completed the task of a contest - 3 war attacks. After big problems, I got into the war zone. I started 3 attacks (I did it after more than 10 attempts). I got some war points. I lost all the energy even though the attacks still had some energy to keep. No one of these attacks was counted in the contest. I lost my task in the contest. I can no longer get to the war zone, but my city is filled with green houses.
The same problems with slow and access to the GlobalHQ, Chat and War Zone are reported by other players in my club.
