I gave up waiting and got the ad supported version from the Android Market. All progress was preserved, and I was able to start working on the new levels. I was about half way through getting 3 stars on them when I saw the FB post from Amazon saying they finally had the updated version.
I decided to try to install the Amazon version over my existing one, hoping once again that my progress would be saved and the ads would just go away. Wrong. I don't know how it happened, but the one I got from Amazon reverted me back to St. Patrick's Day with no progress saved, even for older seasons. I'm back to square one! And both markets show I'm up to date. So I uninstalled it, but now the "Install" button on Amazon does absolutely nothing. Guess I have to install the ad version again and replay everything. I could kick myself for not taking a nandroid or doing a Titanium Backup first!
