content: Its all about the upgrading to a pay service. I thought when I first got an email and opened it about this new app from Adobe Acrobat telling me that they had added all kinds of features. I thought finally this will be so much easier now to send and receive PDFs that u can edit and sign and thats way cool. Then when I went to use it. Bamm the first thing they hit u with is a subscription for premium. Cause low and behold the app doesnt do very much unless you upgrade to premium. Sucks
