This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all requested changes or keep discussing them.

Thank you.

==> I am sorry I didn't find the missing advice you said. Could you explain it again?

Rob asked - Commit msg should explain reason for breaking users.
