Doesn’t work – USA Holidays 2013 - 2017 Calendar and Events Countdown Review

I love this app it works very well most of the time but now it doesn’t work at all and now it just keeps saying app needs to be updated to work with iOS 11. Hopefully it will get fixed very soon because I really enjoyed it when it used to work ?
