Hi @Oliver !
Gatsby is somehwat unique in that it does not have run a local server, and as a result it is difficult to get real time changes to display on your app. Any time you make a change and want to show it on your deployed site, you would need to re-run your gatsby build to generate your static pages.
Some users have used this flow: Avoid having to stop and start GatsbyJS development server to get changes from Builder.io
To set up a webhook and re-deploy automatically after each publish event. Try that out and see if that works for you!
