There are a variety of reasons why the 360ETC assistant on your phone suddenly can't check the balance or charge the value. First, it may be due to a temporary problem with software or network connection. In addition, if the balance of the bound bank card is insufficient, it may cause the deduction to fail. In addition, it may be because the top-up platform is provided by the National Road Network Center, and the 360 driving assistant APP is only the data receiver, and it needs to wait for the National Road network Center to return data before it can be updated, and there may be delays during this period.
