I re-subscribed to Amazon Prime a few weeks ago and I received a link to a free magazine online using Kindle. I have Kindle on my iPhone. I opened the APP to read the mag but it won't open. I see a brief flash of the mag title on the Kindle app but it immediately defaults to a book (Think and Grow Rich ) I downloaded a while ago. If I swipe left, right , up or down.... I can't get rid of it. I turned the phone on and off, closed the App and reopened it and book still appears. How do I get out of the book and open the mag? I can delete the app and reload it, but I am assuming that I am probably overlooking something simple.
