• When you see the window with the choice: You’ll see two options with a preview of your level and coins—one from the server (the game’s storage) and one from your device.
• Why it matters: If something unexpected happens to your device, you can choose the progress saved on the server to avoid losing any progress.

Which to choose: To keep the most progress, pick the option with the higher level and more coins. This way, you’ll stay at your latest point in the game.
