Dear soldiers,

We are going to take a maintenance for IOS servers at 00:00 on Oct. 21th PDT, 2019 to solve the login issue of Facebook on IOS 13. It will take about 1 hour. During the maintenance, servers will be closed and you cannot login the game. If maintenance is completed sooner than expected, the game will available at an earlier time

Thanks for your time and understanding.
