    Hello,

    When I tried to access a User and tried to save the changes I made, I came across this error: 

    PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class WC_Piraeusbank_Gateway does not have a method "add_woocommerce_customer_meta_fields" in /var/www/vhosts/../wp-includes/class-wp-hook.php:310

    I tried to find the function that is called but nothing was found except from the filter.

    Can you please check this and update the plugin?

    Thank you
