A breakthrough! Having seen another post comment, I changed the ACF date & file fields to Text and the values passed through and are visible in the backend.
It works, but is this the best way of achieving this? It means that the GF form does the validation work before storing the ACF fields as text. If I use the WP backend to add Minutes, I’d need to enter text without the date/file validation that those field-types give?
