Hi @it40,
I’ve tested Gutenberg with each release and every time I test just two things – whether or not I can manipulate my text and handle images as easily as the Classic editor. The answer for me is still no (at the time if writing). Unfortunately a multi-paragraph text model was not chosen. I haven’t moved beyond this to extensively testing embeds.
I don’t consider myself a developer but I’ve been working with WordPress since 2006 and know my way around the code. I am always happy to help others if I can but this is not the forum for that. I haven’t used the Snax plugin before and suggest contacting Snax support. Likewise for DigitalOcean. Contact me on Slack if you think I can be of any further help – @padraigobeirn
Also, don’t forget that you can install the Classic Editor plugin which will block Gutenberg (no pun intended ??) for the next couple of years. https://www.ads-software.com/plugins/classic-editor/
