My Prezi Viewer never updated! – Prezi Viewer Review

My Prezi app we'd in mid update and never completed. I have updated all other apps and my iPhone 6s Plus numerous times. I have tried to delete and it will not delete. It is currently in a greed out state and I even tried going to the App Store to open it. I'm stuck with this unusable app on my phone until the next update I suppose.
