1. Check the network connection: Make sure that the mobile phone or device is connected to a reliable network, such as Wi-Fi or mobile data network, and the network connection is unstable or the signal is weak, which causes the applet to fail to load or open normally.
2. Clean up the cache: find the application management or application list in the settings of the mobile phone, find the Wal-Mart applet and enter its application information page, find the storage or cache options, clean up the related cache files, and reopen the applet to see if it can be loaded normally.
