Last update

My iPhone is set for auto updates. Every since the March 25, 2017 update my icon has disappeared and I am unable to open the app. According to settings I still have the app on my phone and when I go to Apple Store it shows update but will not let me open the app. Cant delete and re-download and cant open. Fix this NOW!! Want my app back! This is BS!!! ???????
