Change cancellation policy once the booking is made

[Nico56]

Hello, 

I just listed my place and by mistake I chose "flexible cancellation policy". Now my place is booked and I need to change it to "strict".

I have asked the guests and they are ok with the change. However I cannot find how to change it, and if either of us (host or guest) cancels the booking will have to pay the service fee as a penalty.

Can someone explain to me how to do it?

Thanks

@Nico56 Short answer is: you can’t. Policy at the time of reservation is the policy that sticks.
