A. Ensure your device has sufficient free memory by closing other apps running in the background. Restart your device to clear temporary files and refresh system resources. If the problem persists, try clearing the app cache by going to Settings > Apps > 99 Restaurants > Storage > Clear Cache.

B. If clearing the cache does not resolve the issue, consider uninstalling and reinstalling the app to ensure you have the latest version and that any corrupted files are replaced.
