@sim50 Hi and welcome, If you have been playing without logging in your progress is not being saved. you may find that if you have the error above explained by @kiara_wael you will need to uninstall and reinstall the game. but as your progress is not being saved you would need to contact customer support to get your levels manually restored to your account.
Thank you
