A. Ensure that you have a stable internet connection before downloading the app. If you encounter issues, try restarting your device and clearing the cache of the Google Play Store. To clear the cache, go to Settings > Apps > Google Play Store > Storage > Clear Cache. After that, attempt to download the app again.
B. If the app is not downloading, check your device's storage space. Go to Settings > Storage to see if you have enough space. If not, delete unnecessary files or apps to free up space and try downloading again.
