Gutenberg is not compatible with any remote publishing, that is not designed specifically for it. This was the first observation me and others made when gutenberg 1.0 released. Everybody that uses remote publishing will have to ask its author to update it to support gutenberg.

... but its actually even worse, as gutenberg do not support displaying block information in a human readable way, every new block you will add to your site will be a case of hit and miss if you will need to edit it remotely without using a browser for it.
