kanara.ali, when you launch the app, you are given a choice to either start the wallpapers or choose wallpapers. First, you need to tap on "Choose" and then select the downloaded wallpapers. After that, close the app and open it again. This time, select the first option. Then wait for 10–15 seconds, and the wallpapers will be set automatically.
