Unity Tilemap 2D player getting stuck in a platform - unity3d

the question is quite simple. I have this platform and I do not want the player to collide with it when it jumps on the side or under it. In my Tilemap I have already added a composite collider 2D to the collider, so it doesn't separate each tile into a different collider.
As you can see, there are 2 tilesets but 1 collider thanks to the composite collider 2D. I have also changed the physics of this tileset, which is why the collider is so small (which is intended) so that the player can walk under it with no issues: Ej
However, when I jump to try to reach it by side, it does collide, ignoring the side arc function. I have never used a side arc, so I'm not sure if it should be done like this.
This is what happens instead of going through the platform it collides with it ... I thought Side Arc would let me go through the platform if I go by the sides, which is what the logic of the statement of a side arc would do but I guess I was wrong.
it gets stuck instead of going through, so what am I missing or doing wrong ?
I know I could simply hardcode it by making it trigger and when the "ground" collider attached to my pj touch it remove the trigger but I wanted to know if it was possible without that.

Understanding what causes collision events

https://docs.unity3d.com/2021.1/Documentation/Manual/CollidersOverview.html
While getting some basic collision detection set up I referenced the official docs on the matter. Unfortunately, this left me more confused than when I started.
I made a simple scene. In this scene I added a sphere with a sphere collider (non-trigger) and a Kinematic Rigidbody. A script moves this object on the X axis when played.
I then created cube with a box collider (non-trigger). This object has no rigidbody or scripts attached.
Looking at the chart in the documentation linked to above, this should fall under the Static Collider and Kinematic Rigidbody Collider interaction, which should not create collision events.
However, if I add a OnCollisionEnter() to the sphere, it will call this method when the objects collide. Without physics they both continue on their way, otherwise oblivious to each other.
My concern then is that either the documentation isn't entirely correct or I have a fundamental misunderstanding of what it is telling me.
What's going on here?

Having one hitbox for Tilemap

I'm trying to make a one way tilemap with platform efector, there is a problem though, because the tilemap collider makes each tile have a collider, the player sticks mid way through the platform if he tries to move because of the colliders, like here OneWayTiles, the player can get through but can't go left or right because he gets stuck, I did figure out that if I take the sprites and make them a prefab they work, I put the box collider and the platform effector on the parent and it works with no problems,
like here, so I do have a solution but it will just take too long drag and drop and change the size if I have to, is there a way I can keep it as a tilemap while not having this problem? thanks in advance.

Unity - How to give some flexibility to colliders

Hi I'am new to Unity and I was trying to implement a game using tetris blocks.
The game's goal is to build the highest tower before it collapses. However there is a problem in my implementation which is seen in the picture below.
I achieve the building a tower task by activating the rigidbody gravityscale when it collides with something. With that way it can collapse after touching somewhere not before. But I want to have the flexibility of some collisions. In the situation seen in the picture below, that 'T' block will collide with the point in the red circle before landing safely and gravityscale of the rigidbody will be set. So it will drop but I don't want it to happen becasue the collision area is too small. I want to make it land safely with some flexibility.
I tried to make colliders' size 0.9 but that just disrupts the scale of the world.
Can I do something like this :
If collision happens, check collision area and if the area is lower than lets say 0.1, do not trigger rigidbody gravityscale.
what about using capsulle collider 2D with small radius?

Setting up a sliding character in the right way

I would like to try and make a game similar to Altos Adventure. I am having trouble starting.
How to set up the terrain so that my character doesnt get stuck?
I simply drew a test sprite for the ground in photoshop. What collider2d should I use?
I use polygon collider and reduce friction in the material. But the character gets stuck, hits small invisible bumbs and it feels awful. The worst part is connecting 2 ground sprites together! The point where they connect is always messy.
I have a question for the future as well. How would I add the endless part of the game?
Would having many "pieces" set up and just spawning them as the player rides down work?
I havent written any code yet as the problem is simply in the physics in my opinion.
Thanks to anyone who takes the time and tries to help!
To move your player use rigid body.AddForce(Vector3 direction, ForceMode forceMode); then create a Physics Material with friction = 0 and put it in your player's collider.

Climb down ladder in 2D platformer game

For my game, the player character requires to climb up and down ladders those are placed in the gameplay area.
At present, I can able to climb up for my player character to climb down at present I don't have anyway. Because platform box collider applied with platform effector, so for the climb up, effector does not create any problem but now after reaching the top, it becomes solid platform so now I can't able to move downside.
For climbing up, I have followed this tutorial: How To Make 2D Ladders In Unity - Easy Tutorial
I am looking to implement some physics so I can reach downside to the ladder after reaching top.
You need 2 boolean variables isClimbingUp and isClimbingDown which depend on pressed key and a second ray, which will check -Vector2.up direction. Then just add one more 'else if' statement for down direction.
Yes, I have managed to solve this, and the game is published in the stores.
You can check using the below link:
Humpty Trumpty's Border Wall
This is my overall physics setup for the stair:
I have applied a trigger collider to my stair object and disable player gravity scale when the player within the stair.
Then after within the trigger enter and exist, I have done this:
Physics2D.IgnoreCollision(m_CapsuleCollider, myStair.platformCollider, false);
Disable collision between player and platform colliders when the player is within the stair.
I don't think, Platform Effect 2D becomes useful to me in this process but I didn't remove this to remain in the safer side.
So you have to keep a reference of the platform object which is attached to Stair.
I hope you will get a general idea to solve this problem.
