Background of the issue:
I'm using WPML with ACF and ACFML bridge plugin with 2 languages. When I use the ACF API update_field function to update a custom field with the ACFML preference set to Copy, it does not update the field value in the other language. When I edit the post in the WP admin, the new value is copied to the other language. I am only asking about the ACF API update_field function.
Symptoms:
The ACF API update_field function does not update the custom field value in the other language, even though the ACFML preference is set to Copy.
Questions:
Should update_field update the custom field in all languages if the preference is set to Copy?
Is this behavior a bug or something that is not expected to happen?
