To be honest, I think it was buggy on windows as well.

I’m also interested in this. In my old xps 13 the s0 was very buggy. Would be a shame if you can’t switch to s3 at all. I thought it was a limitation of the x86 architecture actually?

I don’t know about kobo but with koreader you can use OPDS as a source. They also have a specific plugin for wireless calibre connection.

Note for koreader you can hook it up to kavita or audiobookshelf to download books wirelessly. I’m mainly annoyed by the manual calibre step. I have to do the same thing to remove drm, any idea if it can be automated?
