Why can't I play with my Friend who is on Android?

When we get an update ready we release it to both Android and iOS. Google Play Store publishes the update almost immediately. It takes App Store few days to publish an update. Meanwhile we can only wait.

Sometimes the old and new versions don't work together. That is why you can't play with a friend (who is on Android). As soon as you both have the same version of the game you can play together again!
