Dear June
Once again kindly login to your Airbnb back office. Select the hosting mode, if you are in traveling mode. Then select host, after that go to your listing check the all details and go to until end then save it or if ask for publish, click on publish.
Although your listing publish in Airbnb web server but some time need time to refresh to others network server. Your husband can try another option restart his device and try again to find it or using any web browser can try also like, Chrome, Internet Explorer, Mozilla Firefox, Safari etc.
There are so many way you could find your property in Airbnb listing.
Hope you can find your property now.
Regards
Mizanur
