Why does the standing reminder suddenly pop up on the Xiaomi Smart Band 8 when just started the activity?

Certain conditions are required to determine the standing reminder. If you receive a standing reminder from the band just after you start your activity, it is because you are in an active state but have not reached the threshold of standing behavior. You can continue to move and ignore the alert. If this phenomenon occurs frequently, you can submit user feedback on the Mi Fitness APP. We are constantly optimizing the algorithms related to standing determination to gradually improve the user experience.
