Problems with Paypal

The default woocommerce currency I have for products is USD. I configured the plugin for Colombia to show and work with COP, and in the rest of the world with USD.

I have two payment methods, Colombian payment method (Payu) and Paypal, everything works perfect but when I try to pay with Paypal in Colombia it sends the currency as COP and I need it to be sent as USD at that moment, that is, Paypal omit your plugin settings.

I tried doing this:

function wpcc_change_currency($paypal_args)
{
if ($paypal_args['currency_code'] == 'COP') {
    $convert_rate = 3666; //set the converting rate
    $paypal_args['currency_code'] = 'USD'; //change Pen to USD
    $i = 1;

    while (isset($paypal_args['amount_' . $i])) {
        $paypal_args['amount_' . $i] = round($paypal_args['amount_' . $i] / $convert_rate, 2);
        ++$i;
    }

    if (isset($paypal_args['tax_cart'])) {
        $paypal_args['tax_cart'] = round($paypal_args['tax_cart'] / $convert_rate, 2);
    }

    if (isset($paypal_args['shipping_1'])) {
        $paypal_args['shipping_1'] = round($paypal_args['shipping_1'] / $convert_rate, 2);
    }

    if ($paypal_args['discount_amount_cart'] > 0) {
        $paypal_args['discount_amount_cart'] = round($paypal_args['discount_amount_cart'] / $convert_rate, 2);
    }
}
return $paypal_args;
}

But it doesn’t work, that code doesn’t really change anything, is there a way to configure the plugin so that it doesn’t affect paypal? I need PayPal to always work with USD and default prices.
