A. 1. Update the app: Ensure that you have the latest version of the SMARTY app installed. Go to your device's app store, search for SMARTY, and check for updates. 2. Clear app cache: Go to Settings > Apps > SMARTY > Storage and select 'Clear cache'. This can help resolve issues caused by corrupted data. 3. Reinstall the app: If clearing the cache doesn't work, uninstall the app and then reinstall it from the app store. This can fix any underlying issues with the app. 4. Check device storage: Ensure that your device has enough storage space available. Go to Settings > Storage and check if you need to free up space.
