Upgrading to MLO2 Pro via Google Play

[Tze-Yiu Yong]

Hello and Happy New Year from Oregon!  I purchased MLO1 Android from the website and then, took the free upgrade to MLO2 PRO (I believe thru Google Play).  I am impressed with the features in the new release and, now that my PRO Trial is over, would like to purchase MLO2 PRO Android thru Google Play.  Has anyone tried this?  When I go to Registration in the Main Menu to upgrade to Pro on my phone, the only option I'm presented with is purchasing the upgrade from MLO's website, not Google Play.  Why isn't the Google Play option presented as well?
