Hi,
actually, it's good as is already. I think I know what happened, you need to redownload it, because I think I originally posted the verison you had and realized my mistake and corrected it straight away. Cause the physics2dIgnoreCollision is indeed not with layer but with colliders.
can you double check this on your end? delete Physics2dIgnoreCollision action and redownload it.
Bye,
Jean
