@Kevin-And-Linda0 Have you reported this issue through the site feedback link? If not, do so immediately and often. You will not get a response, but someone somewhere might tell the programmers to fix it. Don't hold your breath, as I have found that unless some mucky-muck within the company has noticed and been bothered by the loss of a "website amenity" it will not be fixed.
I have complained and actually had a conversation with two of AirBnB's website programmers about the ADA compliance of the calendar -- which I cannot read due to the greyscale used -- and NOTHING HAPPENED even though I demonstrated how the calendar was unreadable and that a simple change to the text color code and bold outlining of the date boxes would suffice.
