After the shift to wintertime on the last Sunday in October the game seems to have been desynchronized: it goes on for a whole day, assigning the results of the present day to the previous day.
The fact that the game credits the steps of the present day to the previous day means that I always lose the bonus i gained with Powerups.
Today 1 nov. I did about 400 steps but no step is marked
Yesterday 31 oct. i did over 13k steps but the game reports the 400 steps I did TODAY
On 30 nov. the game reports the 13k steps I did on 31 nov.
