Yes indeed, but I don’t know if I’d need both hands to count the number if Americans I’ve heard use “whom” in a sentence outside of English class, let alone used it correctly. I don’t even feel I see it written often here.

American here: no idea how or when to use whom. Keep reading about it, but, uh, can never remember which is which.

I only had one teacher that taught it well, so I’m glad I liked her as a teacher and paid attention.
Who/whom and I/me I find work well when trying to make substitutions.
