I’ve updated some ACF fields in user section via an ajax call using update_field() fonction.

update_field('field_name', 'field_value', 'user_' . $user_id);

When i take a look in the admin panel, everything is fine, but in front, i don’t have any values.
In order to get those values i need to manualy save/update user in the back office.

In my template i use :

get_field('field_name','user_'.$user_id);

Any tips or advice ?

Thx in advance
