About the Android version
Unfortunately we cannot publish the Android version because it is based on a framework version that Google does not accept. To upgrade the app a lot of changes are needed and another round of pre-releases, and therefore there will not be a 2.9 version for Google Play. You may however download the official APK directly from there: Android 2.9 Official Release
This is the reality of app stores in general - small developers being imposed never ending new requirements by all-powerful companies, and by the time a version is finally ready we can't even publish it because yet more requirements are in place.
