"...that they might change their minds about leaving four stars when they see the prompts. Does that mean they can go back and change their four to five stars?"
Being able to change the star rate is only possible if they haven't submitted the review yet.
Or if they were the first to submit and then go back to amend it within the 2-day edit window BEFORE the host submits in the meantime. (Obviously I'm assuming that guests get the same chance to edit their review until 48 hrs later as long as the other party hasn't made a review and both go public.)
The big question is probably - does the guest even know that...
And well, we could use the same principle as guests and just type into their private feedback "Odours", but no, we're too professional to do that! But joking about it certainly aleviates the tension!!
Regarding the star rating not being visible on the guests's profiles -
when I joined Airbnb forums, and this was mainly before CC there was a brilliant suggestion which I wouldn't apply to most guests, and actually never have: stating it in the text.
However it's moth-balled in my review toolbox in case I deem it the best way to handle a guest review!:
'Guest was lovely and friendly. Communication 4 stars, Cleanliness 4 stars, Followed House Rules 5 stars...'
