Hello, ArturTuRocK ,
Just for information, I will clarify that the mileage counter A can be reset only on the Statistics tab by clicking on the circular arrow opposite the unit’s mileage.
If there is a problem with resetting the mileage, write to us at firstname.lastname@example.org, indicating the login and unit ID, we will try to check it additionally.
Also, if possible, please send a video where you are trying to reset your mileage.
It is important for us to understand whether an error appears and what behaviour of the system at this moment.
