2D custom sort axis not working at all

Hello everyone. I really need help, I've been struggling with this for 2 days, browsing all the internet, forums, answers, discord servers, to find a solution, without success.

Context I have experience with Unity, however not with tilemaps, so I am making a classic top-down 2D game using tilemaps and I need a way for objects to appear in front or behind other objects depending on their Y position.

Actual problem I tried many ways and none worked, really none. I followed tutorials and posts and most say to use the custom transparency sorting axis to orthographic with 0, 1, 0, which I did, but it doesn't work, it never works, I tried on different scenes, different projects, different versions of Unity, tons of settings for the camera, sprites, tilemaps, I even tried to set it via script, I just can't get it to work, it just will never render them the correct way depeding on their position.

Please I'm really hopeless, I don't know why it works for everyone except me, I do'nt know which setting I missed, I really need help, please
