Why can't I use my paid app without an Internet connection?

The first time you open a paid app, you need an Internet connection to verify whether the app was successfully purchased. After that, you only need to connect to the Internet to verify again if you have not connected to the Internet or used the app for a relatively long time (seven days or longer). If you find that you are frequently unable to use a paid app without an Internet connection, try updating AppGallery to the latest version.
