I-140 approval notice returned as undeliverable

[Bomber]

I got an approval email from CRIS last week on my I-140.

Today I received an email saying the notice that USCIS sent was returned as undeliverable.
Any one has similar experience? Where does the I-140 approval notice go- Attorney or Employer address?

Thanks

Usually it goes to both. Original to Attorney with a courtesy copy to Employer
