@Mert123 Hi and welcome, If you progress is still on the one device sounds like a connection issue. Are you sure you are signing into the correct account.
If your new phone has no boosters or lives (you will LOSE these if you do this ) that are saved, please try uninstalling the game and restart your device and then reinstall the game and log in to your account and see if this syncs your progress correctly . if it does not please try playing a level and see if this forces your game to sync
Barring that please see post below for getting your levels restored
Thank you
