Unfortunately, Amazon adds their own special DRM in the version distributed through their store, so I don't have a way of distributing an installer for users that purchased through the Amazon App Store. If you'd like to help test, you'd need to backup your library, uninstall the Amazon App Store version, install the beta version, wait to fail the license check, I can allow your device to bypass the license check, and then you can continue testing. When the beta is over, you'd need to uninstall and reinstall the app off the Amazon App Store so you can get regular updates. Let me know if you'd like to do that.
