UI buttons are not working on device build.

I am working on an AR project, where i am placing down a car on the scanned plane. The placing is happening after i tap on the screen, and that is working fine. I am checking if the tap is not happening on any of the UI buttons (with EventSyste.current.IsPointerOverGameObject()), and that is working as well.

I want to control the car with UI buttons, wich are working in unity, i can click on them, and the car will move as intended based on what i pressed. However when i build the app and i click on the UI buttons on my phone, nothing is happening. I logged out some things, and for some reason on mobile the OnAccelerate, OnTurnLeft, etc... functions are not called (the log is made inside them), meanwhile in Unity they are being logged as shown in the picture below:

I am using the "new" input system, and the massage sending behavior based on the arrow keys:
The input actions:


The UI buttons are all On-Screen buttons with the control path set as in the input actions asset.

My EventSystem:

I have tried changing the pointer behavior.

What could be the problem here?
Thanks in advance!

 

I'm going through something very similar, as I'm translating a VR game to the Oculus Quest 2. I have a UI button that is working within the Unity Editor, but once I build it to the headset, the button does not work, and I'm sure it is because certain functions are not being called. I am in the process of figuring out what exactly is not being called and why.
