Can't email – Microsoft PowerPoint Review

Using this mobile app for the iPhone. They've made it impossible to easily share power points through email. It should be so obvious and easy that anyone can figure it out. Please fix. Figuring out the trick won't help because it will be a b*+€h to figure out next time when I forget. PLEASE FIX! Finishing a power point on my phone does me no good if I can't get it off my phone.
