Under the House Rules settings, if a host selects NO to either or both of the settings concerning suitabilty for children (one for ages 2-12 and the other for ages 0-2), that clearly indicates that the property is NOT suitable for those ages. However, on the listing page itself, which guests see, the rule reads "MAY not be suitable..." (emphasis mine). This is 100% incorrect and is highly misleading.
The fix for this is incredibly simple, not involving the underlying code logic. Simply delete the word "May", change the first letter of "not" to uppercase, and delete the word "be". Done! Of course, I suppose the identical fix might have to be made in three separate locations, which is still not all that hard.
Please have someone edit that text, AirBnB.
By the way, when I reported this bug via @AirbnbHelp, the response I received made it clear that the support person didn't even understand the issue. Or didn't read past the first sentence of my brief message.
By the way #2, someone else had posted this same issue here a couple of months ago. That post received only 16 Thumbs-Up, so it got archived instead of being forwarded to AirBnB. If this issue matters to you, please click the thumb! Thanks.
