First, it is recommended to check if the device network is stable, try switching Wi-Fi/mobile data and then reopen the APP; if the network is normal, you can try clearing the APP cache (path: Mobile Settings - App Management - Corresponding APP - Clear Cache) or restart the device; if the problem is still not resolved, you can feedback the problem through the in-APP customer service center or technical support hotline, inform the device model, system version and the scenario where the problem occurs, and we will quickly troubleshoot and provide a solution.
