Not working if want to use existing photo – Insta Shapes Pro - Snap pics and shape photos with groovy patterns, ig symbols & fab deco shapes! Review

I downloaded the free version at first. It was ok since it did not have high resolution. So I choose to pay for the pro version. Then I found out I could not use existing picture!!!!!! That is a BUG that need to be fixed!!!!!!!! Or I paid for nothing!!! I am using iPhone 7 Plus with iOS 11.4
