First, let’s cover the basics: make sure your save option is “Paper background.” The highlighter doesn’t render onto a transparent background.

If you have the right option selected but you are still experiencing the problem, you may be the victim of an issue with the last update. For some unknown reason, when you upgrade to 6.2.30, the highlighter doesn’t get exported to PDF. Resetting the app will solve the problem.

First, open the app Settings, and make sure your Save Location is NOT to the Local App Folder, or you will be losing your data!

Press Ctrl+Shift+R, then select Reset App Data and Exit.

The app should now save the highlighter correctly for new notes.

For existing notes, you will need to force the saving of the pages where the highlighter doesn’t save correctly.
