Hello @pischa75 and welcome to the community. Are you referring to the Daily Calendar or the Daily wheel? If you log in every day you should progress through the various boosters available in the Daily Calendar. It's best if you log in roughly the same time each day. I have noticed that if I log in late evening - the game will think it is the next day, If you are not getting the next reward each day - you need to make sure you have the latest version of the game and that your cache is cleared. Then I would do a hard restart of your platform (PC or mobile) and see if that clears up the problem.
