Question / bug report
When using the plugin to try to remove Kobo DRM it gives strange behavior, potentially does not recognize that the book has a drm based on how I understand the menu:
File is openable in Calibre, but is not readable:
report is shown with 10.0.3 but I tried 10.0.9 first and got the same issue

Try closing Kobo Desktop before opening Obok. The book should have a red closed lock. Otherwise it will be imported unchanged. This book isn't Kobo Plus?
Closing Kobo and importing the book again did fix it, thank you. Might be something to consider adding to the instructions though.
