I’m using
update_sub_field( array('subscribers_lists',$field_row,'subscribers'), $current_subscribers );
to update certain custom fields.
Everything works as expected except when $current_subscribers has 'n'or <br> – it won’t do a new line as I would expect.
How would I force a new line when adding text to a field using ACF?
Talked with some developers and they said you cannot do this with a normal text field or textarea. You have to use WYSIWYG field instead.
