When I upload from pdf or copy/paste text, for some reason a whole lot of periods are left out, which ruins the pacing. Also I thought it was lagging put because I was on 5G...but even on gigabit wireless I can't get more than three paragraphs without the app completely failing No wonder the trial period is pretty much a day, if you use this app for more than 5 minutes you will scoff at the idea of paying a hundred plus dollars for it
