Amazon has been very aggressive in updating the DRM used for KFX format. Each time that a solution for KFX DRM has been added to the DeDRM plugin Amazon has blocked it by quickly switching to a new DRM scheme.

At this time DRM removal for KFX books on Kindle devices only works if the device is running firmware version 5.12.1 (released in 2019) or earlier.
