Q.Japanese Acer Not Coming Into Leaf.
Last summer I purchased a Japanese Acer in very good health. It was pot bound so I repotted and it thrived. It is situated in a container in sheltered a basement yard on the coast. It does get a little sunlight late morning then it’s shady. This spring new shoots started to appear but they have never developed. I understand that veriticillium wilt can be a problem but there are no signs of dark areas of wood when a branch is cut, just white with a green centre. There is no signs of any pests. I have repotted taking the old compost off the root ball putting it into ericaceous compost. I am baffled any ideas anyone would be welcome. Thank you Glenn

Unfortunately, your photo did not come through. I am unable to see the damage, and container that it is in.
Likely there are a few things that could have happened. If this was planted in compost, alone, without amending it with top soil or potting soil then I suspect drastic overfeeding. Hot soil will burn roots, and keep the tree from recovering from the transplant shock.
If there is life left in the tree, then there may be a chance to bring it back. If the tree is brittle, then it will be best to start over.
