Can I switch from Apple Pay to Google play without starting over to take advantage of coupons?

If your game is connected to Facebook, you're supposed to be able to switch between devices. Make sure Apple game is connected to FB. Always have your game user ID in case you need help from Wooga support. Then on Android device, log into same Facebook account. Find JJ app in Google Play and install. Connect it to FB and it should give you a choice to start over or use game in progress. Be sure you select the game in progress; if you select start over, you will lose the Apple game as well.
