I feel your pain having had a similar experience (lost drone) - I wonder how many incidents result in an unrecoverable Anafi (and flight logs). I have contacted Parrot regards warranty and so far it has been a data gathering process - with the last email wanting a picture of the damaged Anafi - D'Oh!
How long have you had the Anafi / number of flights?
Did it fall straight down or veer off to one side?
