Hello @Deepak Patel ,

Welcome to Microsoft Q&A!

Please check if your purchase has been completed. If the license is inactive, it is likely that it has not been purchased yet.

Please use StoreContext.RequestPurchaseAsync to purchase the application.

private async Task PromptUserToPurchaseAsync()
{
    // Request a purchase of the subscription product. If a trial is available it will be offered 
    // to the customer. Otherwise, the non-trial SKU will be offered.
    StorePurchaseResult result = await subscriptionStoreProduct.RequestPurchaseAsync();
    // Capture the error message for the operation, if any.
    string extendedError = string.Empty;
    if (result.ExtendedError != null)
    {
        extendedError = result.ExtendedError.Message;
    }
    switch (result.Status)
    {
        case StorePurchaseStatus.Succeeded:
            // Show a UI to acknowledge that the customer has purchased your subscription 
            // and unlock the features of the subscription. 
            break;
        case StorePurchaseStatus.NotPurchased:
            System.Diagnostics.Debug.WriteLine("The purchase did not complete. " +
                "The customer may have cancelled the purchase. ExtendedError: " + extendedError);
            break;
        case StorePurchaseStatus.ServerError:
        case StorePurchaseStatus.NetworkError:
            System.Diagnostics.Debug.WriteLine("The purchase was unsuccessful due to a server or network error. " +
                "ExtendedError: " + extendedError);
            break;
        case StorePurchaseStatus.AlreadyPurchased:
            System.Diagnostics.Debug.WriteLine("The customer already owns this subscription." +
                    "ExtendedError: " + extendedError);
            break;
    }
}

Thank you.
