Recent browser versions support the hyphens CSS property to enable hyphenation. If you want to the finer control over hyphenation that wp-Typography offers, make sure that the your theme stylesheet does not contain
hyphens: auto;
(or one of its vendor-prefixed variants like -webkit-hyphens). If you can’t remove the property from the theme’s stylesheet, make sure to add
hyphens: manual;
in a child theme stylesheet or wp-Typography’s injected CSS. (Don’t forget the vendor-prefixed variations!)
