I have calibre 8.4.0
I have added the No/Dedrm fork autorelease version (its still shows up as 10.0.9 though when looking at installed plugins)
I have the KFX input 2.25.0 plug in installed
I have my kindle keyboard serial number added to NoDRM

I got a book I bought from amazon and had it sent to my kindle keyboard and I got it as a azw3 file.

Plug my kindle into the PC via usb added the book to my calibre library however when I try converting from azw3 to mobi it gives me an error CANNOT CONVERT: book is locked by drm.

The book is fairly new as it released in April 24 2025.

Any tips?
