Hi @Jo10,
1) Airbnb refunds the guest dependant on your cancellation policy which is "flexible".
"If the guest arrives and decides to leave early, the nights not spent 24 hours after the official cancellation are 100% refunded."
2) They might get a day back IF they cancel.
3) If they do not cancel, they may be able to plead with Airbnb that they notified you thinking that was enough. Airbnb does seem on the guest's side lately when making decisions. I would strongly suggest you cantact the guest and tell them they need to cancel and that you cannot do this for them. The reason a say this is if the guest cancels, they cannot review you which would probably be a good thing as they may post a "revenge review".
@Jo10, I would consider changing your cancellation policy to at least moderate.
