Matthew, thank you for looking into this. I appreciate the effort.
I have investigated some more. Here is what happens: On Firefox, on my wife's laptop only, when one first does a search for "Pflugerville", our property does not show. This is usual: too many properties and hence not all show up. Then I zoom. No new properties show up. In red, but hard to see since we all learn to filter out clutter, a notice appears that says something like "Refresh Search." Clicking on this then pops up new properties. After zooming a few times, low and behold: the property shows up. So, the problem really is that depending on one's setup, zooming either automatically refreshes the search, or it doesn't.
Conclusion: the system works, but was not intuitive to us. Problem solved.
As for the response you mention: yes, after posting the response I realized that the review that they gave was a private review. It is not very intuitive to me what becomes public and what doesn't. In fact, I still don't know when the score shows up or if it does. And over time this seems to have changed even. Naturally, we would prefer to now take that response down.
What is still puzzling is that this property only gets 10-15 views per 30 days, in a very busy market. We have another property in the middle of nowhere in Pennsylvania, where there is little reason for anyone to travel, and it gets 250 views per 30 days.
Anyway, we are learning!
