as in the images appears: the first picture is the bake normal and rendered, and as you can see it appears some "seams" around it and with a low height, and in the high poly model you can see the height that it has, so what could be the problem? i ensure that the simple node setup its fine and correct setup.
this pictures shows the optimized model,baked normal, and node setup
this is how it looks all the high poly model details...
