I was just wondering if someone could help me with a question I have. When visiting friends, some of them have a message that comes up that says they have a more updated version of the game than I and would I like to update? There is no update. My question is, is this because I play on a Kindle, which hasn't had the game long, and these others are on different devices, which I assume are more up to date with the game. Would I be correct in my assumption? Any insight would be greatly appreciated, happy gaming.
