Completely confused – Photo Editor: Blur Backgrounds Review

I sorely disappointed I paid $3 for this and I have to delete it . This app was a waste of my time and storage . I read the reviews feeling confident in my purchase and I don’t understand what everyone is happy about . There are no instructions on how to use this app or make it work . I wish there was a way to get a refund ?
