Excuse me, what exactly do you mean? You can try to restart your phone or try it in a good network environment, or you can try the following methods. 1. Find the program in Settings-More Settings-Application-All, click to enter the information interface of the program, and select Clear Cache and Data. 2. It is suggested that you can uninstall the program and download the latest version again. 3. Upgrade in Settings-More Settings-System Update-Detect Update Now. This operation will not lose mobile phone data.
