Hi @yiannisaa, thanks for posting in the Lucid Community! To start, I would recommend checking your Page Settings, by navigating to the Wrench Icon in the app. You can adjust the page size, grid spacing, and margin size to see if this allows you to export successfully without loosing any content.

If the issue persists, I would recommend logging into lucid.app on a desktop to access to the download settings to make more specific adjustments. Let me know if you have any further questions!
