I’m the OP and that is the issue I’m running into. I read on my iPad so I had a different set-up to De-DRM the books but it won’t work under Catalina. I do have an original 1st generation kindle and a paperwhite but even when I download the books for USB xfer using the paperwhite option the books do not have the DRM removed. This is even on books that the publisher has said are being sold without DRM.
