Hey guys! & the rare lady I need some help. I bought my 10.1 specifically for class. My instructors use ppts & I'd rather not have to print them all off. I was just using Polaris 5 and taking notes, using the highlighter function and was LOVING it!! Until it unexpectedly closed on me & didn't save any of my notes. I had the setting checked to save a backup if edits were made but I noticed a pop-up saying save edits weren't available with the document open. Not sure if it was ppt or pptx. I've tried several options in the play store & none do what I want. Any suggestions? I've tried office suite, king something, pearl something. I know that's not specific but my mind is flooded with programs I've tried & anatomy (I'm in class right now)
