I really wanted to like Zinio but have had so many problems with two different subscriptions that would not load (Cycle World and Popumar Mechanics). It doesn't happen every time but I 'lost' 2 or 3 editions from each in the last year.
Zinio CS has been unable to help, simply asking me to remove the app and reload it each time it happens. That worked one time but other than that I have been SOL.
Zinio has been bombarding me with emails urging me to extend my subscriptions but no thanks, I'll stick to my traditional mags on paper from here on out.
