A. 1. Double-check the code: Ensure you are entering the discount code correctly, including any capitalization or special characters. 2. Check expiration dates: Make sure the discount code is still valid and has not expired. 3. Clear app cache: Go to Settings > Apps > Fashion Nova > Storage > Clear Cache to resolve any temporary issues during checkout.

B. 4. Try a different payment method: If the code does not work, try completing the purchase without the code and see if it processes.
