Question 1:
The listing is not available for viewing and the direct search shows it is not in the search system:
https://www.airbnb.com/s/homes?host_id=202873390&map_toggle=true
If you activated it very recently (again), then wait for max 12 more hours (check the link mentioned) if it shows up, otherwise contact Airbnb.Also be sure the listing has available dates to book.
Question 2:
That's a good one, we all suffer from that...
Best regards,
Emiel
