I bought the previous edition. I don't see that you've arranged a free update download. Am I correct about that? Not saying you are obligated to provide it. I think I'm beyond the beginner stage, anyway. Best of luck with it.
No, I hadn't. I did a minor update about a year ago that stayed under the same ASIN so it might be possible to update to that point but this one ended up being almost a complete re-write given all the changes to AMS over the last year including Lockscreen Ads, portfolios, bidding changes, reports, and the new interface/chart.
And thanks for the good wishes. I hadn't intended to update the book again but it got to the point where it was either unpublish the old version or issue a new version. Since I hadn't seen anyone else publish a recent book on the subject I figured might as well issue a new one. If it sells, great. If not, ah well. At least I know it's available for anyone who really needs it.
