Hello, I play the iOS version of the game and I’ve successfully invited a few friends on other iOS devices but I’m also trying to convince a friend that uses BlueStacks and when I sent him the invite he is saying that it just opened up a website for the Apple App Store and he’s not sure how to join using the invite link with BlueStacks and the Google Play Store. Is there another way other than clicking the link in the e-mail, like entering the code after he downloads the game? He searched for Empires and Puzzles and found it but I asked him to hold back on downloading it until I make sure that we can both get rewards Thanks!
