Lumina Support

Find quick troubleshooting steps for Lumina setup, Google Drive sync, PDF annotation, export, and site blocking questions.

Quick checks

1. Open the Lumina side panel from the Chrome toolbar.
2. Select text on a normal web page and choose a highlight color.
3. Open the dashboard to confirm the highlight was saved.
4. For Drive sync, connect Google Drive from Settings and run Sync Now.
5. For PDF files, open the PDF tab and choose a local PDF file.

Common fixes

If highlights do not appear, reload the page and confirm the site is not listed under blocked sites. Chrome system pages, Web Store pages, and restricted browser URLs may not allow content scripts.

If Google Drive sync fails, disconnect and reconnect Drive from Lumina settings, then try Sync Now again.

If a PDF does not open, confirm the file is a local PDF and not an encrypted or restricted document.
