Wont Download Any PDF Files!

I always read reviews before downloading anything and when I saw mostly "great" reviews on this app I was excited UNTIL I downloaded the app ?? It took too long to download anything and when I tried to open any emails with PDF files in them, it would take forever to load and then end up not being able to download at all! Waste of my time.
