Issue when updating custom fields

Hi there,
I am having some issues with ‘Additional wp_usermeta Table Fields’. We followed your directions https://wpfusion.com/documentation/getting-started/syncing-contact-fields/#additional-fields and managed to implement an Additional Field and connect it to our Mautic CRM.

As soon as a new user registers on the platform, metadata is updated on Mautic.

Issue arise when this ‘additional field’ is updated; it does not seem that WP fusion ‘reads’ the field, hence does to update Mautic.

Any idea?
Thanks
