@Nicole194 As you said, your listing doesn't seem to show up. It's tricky, mostly because of the sheer number of listings in your area. But I applied as many filters as possible (after previewing your listing) and then set the dates for an entire (unbooked) 30-day period. Nothing at all showed.
You should probably contact AirBnB. As a weird suggestion in the meantime, try reducing your minimum stay from 30 days to just 28. Logically, that shouldn't make any difference, but it still might. AirBnB considers a "month" to be 28 days, so there might be some goofiness in their code having to do with periods greater than 28 nights.
Good luck!
