Sometimes @Paypal or other merchant company such as Avangate.com, Affiligate.com or Stripe.com needs 1 to 4 hours to verify a transaction before sending information to us. After receiving information from PayPal, license days will be added to your account license. Therefore, when this happens, the process of adding license day to your account license may be delayed 1-4 hours. If you meet this case, don’t hesitate to contact our support team for help.
Please see session of how to add/activate a license or how to apply the license code/gift code.
