There is a time limit, as well as an if-the-other-party-has-posted limit on edits, @Phil-And-Aquilla0 . It is to keep reviewers from changing a review after the fact. Your exclamation point won't change anything substantial, but I do see Airbnb's point with the limits: we cannot all be calling in all the time, and we can't be left on our own to change small things. Changing "can recommend" to "cannot recommend" is a seemingly small thing, after all.
What I do is proofread every review before posting. With my reading glasses on!
I know - it takes time. But it saves leaving a typo, wrong name, etc., on a review.
I wish my guests did that. Then I wouldn't be "Lawrence" all the time 🙂
