@keithlock I am facing same issue updating main group with another group as sub-field.
So it is like
maingroup_subgroup_subgroupfield
If I want to update fields of subgroup, I need to pass maingroup with an array of subgroup and its values,
When maingroup doesn’t exist, and updating fields of subgroup
update_field('maingroup', $values ,$post) it returns true
But when maingroup exists, and updating fields of subgroup
update_field('maingroup', $values ,$post) it returns false
Isn’t there still a native ACF Function to update single field of a group?
