Even when your response or action is late, it’s still worth taking it if you can provide some value.
Someone might be waiting for your reply for a month, but if your feedback can still be meaningful, you should answer regardless of how late it is.
The weekly menu on your restaurant’s website is useful even if you put it up on Tuesday. Ignoring an entire week because you’ve missed the Monday is shortsighted. It only serves to protect your ego (if you don’t put it up at all, people will think it’s by design and not a mistake).
It might be a bit late, but it can still be valuable.
