Should I pay attention to the warning "shader channels normal and tangent.."?

Question

Unity

I've noticed this warning on canvas for a long time.

shader channels normal and tangent are most often used with lighting...

scale mode - scale with screen size
screen match mode - match with or height I'm
using Text Mesh Pro.
It seems that no problems have been found so far, but the warning is a little annoying, and it says that the shader channels are used with lighting, but I don’t have it, my project is generally 2D ...
Should I pay attention to this message? Can it be avoided? Can there be any problems because of this?

Answer 1

As far as I understand, the error says "Shaders are used with light" add light to the scene and that's it.
