Default currency works only after browser refresh

[heiko]

Good day

Added a new hook as per below:

<?php

use WHMCS\Session;

add_hook('ClientAreaPageCart', 1, function($vars) {
    // Provide your new default currency ID
    $currencyId = 2;

    if (!Session::get('uid') && !Session::get('currency')) {
        Session::set('currency', $currencyId);
    }
});

 

The default currency only changes when I press F5 on the browser.  Can you please assist me what I am missing to force the hook to load?

 

Thank you

Heiko
