@Lorraine498 depending on your cancellation reason, Airbnb may apply penalties when you cancel a booking. If you are canceling due to an extenuating circumstance policy, you may be required to provide documentation to Airbnb to support your claim under this policy. So, if you need to initiate a cancellation under the Extenuating Circumstances Policy, you typically need to contact Airbnb support with your reservation details and evidence to support your claim. Hope this helps!
