Every once in a while, I come across something quite unexpected. Let's see who can find the Easter Egg!
***I was only able to make this work with VoiceOver on an iPad running iOS 15.2 so your results may vary.***
1. Navigate to www.airbnb.com and log out if you already have logged in
2. Navigate to the Main Navigation Menu and activate the control to Sign Up. This will open a dialogue
3. Navigate through the dialogue and listen to what VoiceOver says when it comes across the sample phone number. Hint: the phone number begins with XXX.
This may only work in English and it may only work in the United States. If you live outside of the U.S. and use a language other than English, you may have to make some adjustments. There is a button that allows you to make those changes as well.
If you find the Easter Egg, post below in the comments!
