Why can't the shared family account view the map on the Xiaomi Robot Vacuum S40 Pro?

If the shared family account cannot view the map on the Xiaomi Robot Vacuum S40 Pro, please refer to the following information:
  1. This is due to a software bug. Account A shares the home with Account B and gives B admin permissions. After accepting, Account B uses the shared home to add and bind the robot vacuum. However, map encryption is based on Account B, while decryption requires Account A, resulting in a failure to decrypt the map.
  2. Use your own Xiaomi account (the original one) to connect to the robot vacuum in the App.
  3. Updating both the Xiaomi Home App and the robot vacuum firmware to the latest version.
