Remarkable application under WINE (CrossOver Office) has the PDF files added, but does not sync

[ezaton]

I got me a used reMarkable 1. It's a cute device, and I have a large Calibre library. I wanted to upload books to the device, and could not find any updated version which supports Linux. So - I installed the Windows application under CrossOver Office (unsupported, but works well).

The application works. I had to create a symlink from the actual location of the application to ~/.local/share/remarkable/desktop but the plugin seems to work. It creates files in the root directory of the application in the following format:

$ cd ~/.local/share/remarkable/deskto
$ ls

Two PDFs are there. If I take a look at one of them:

The desktop application does not 'see' the new files (and will not sync them to the device). I can manually import the files (from that location) and it will be imported correctly.

Moreover - if I created a directory on my desktop application, the plugin cannot identify it and suggest using it.

I would happily provide any required information.
Thanks!
