Why is the real-time position of the flasher in the same city in Beijing unchanged, or is it your starting position?

There may be a delay in the platform.

Such as server network problems;

Maybe there is something wrong with the flasher's cell phone. For example, the APP in the background will be automatically closed, the mobile phone has not been forgotten, the signal on the road is not good, and the real-time location will not be uploaded;

It may also be that there is something wrong with the APP in your mobile phone, such as some port conflicts.

Personally, don't worry about this problem yet. Although it will take a long time to wait for the express delivery, it has not exceeded the time limit. No, if you are really in a hurry or work overtime, you can communicate with customer service or call the courier.

Ps: It's best to make a phone call to communicate with the flasher, but people may not answer it, because it is difficult to hear the bell when riding a bike without special headphones.
