Thanks for your reply. I would possibly think that would be the case or cause rather however I've seen no change in version number on the server. I haven't seen any downloads or messages regarding game updates. And the last update to come to the Android or iOS store I believe was back in June. I do wish I had the PC version looks so much clearer and more fun.
Game is still fun on mobile and quite addictive. That's why I am spending time to investigate further and ask those such as yourself with much more experience then I.
Thanks again for the response.
