5.6.1 Metahuman body anim and live link face causing split mesh

Having ongoing issues getting a mh to play a body anim and utilise live link face without the head and body meshes separating. Older tutorials on early 5 versions it apparently works but with 5.6.1 the same methods don’t fix this resulting in llf only working on a non animated t pose body or a body anim that over rides the llf. Has anyone solved this issue?

Many thanks
