Hi, We have recently had our bathroom updated and a new Brick nib wall put in and tiled. Within 6 weeks it had cracked on both sides and metal trim had come away. The bathroom renovator came back and replaced the tiles with new adhesive (type used in pools) but I have noticed after 3 weeks it has cracked again and started coming away from trim. Can you advise if this is an adhesive issue or a brick wall issue or something else. Photos attached. Thanks.
