Have you reinstalled the game? Changed your device? Are you playing on two devices? You may need to restore or sync your game progress. Remember, uninstalling the game, just like restarting progress, will cause loss COINS.
The game progress is restored after logging into THE SAME ACCOUNT AS PREVIOUS on Facebook or Google Play Games. When you reinstall the game and log in to THE SAME ACCOUNT AS PREVIOUS on Google Play Games or Facebook, your actual progress should appear automatically.
To do this, go to the “My Profile” section, tap on the icon in the right upper corner, and choose “Settings”. Click on the “Log in” option and log in to the same account as previous.
