Hey, thanks for the report. Yes, this is a known issue with webview extensions in the bottom panel. The team has identified the root cause and is working on a fix.
Temporary workaround: go to Cursor Settings → General → Preferences and change the Default Layout from “Agent” to “Editor”. This should restore Jupyter Variables visibility.
More details: Webview-based extensions fail to render in the bottom panel, but work in the side bar
Let me know if this helps.
