Version 3.9.3 Patch: YouTube Preview Fix in FlowPaper Desktop Publisher

23 November 2025

We’ve released a small but important update to the FlowPaper Desktop Publisher.

Recently, YouTube introduced new security changes that affected how embedded videos load inside third-party applications. This caused YouTube previews to stop appearing when adding video links inside the Desktop Publisher. Today’s update restores full preview functionality. You can once again paste a YouTube link and instantly see the preview inside the editor—no extra steps needed. If you're using video-enhanced publications, make sure to update to the latest version of the Desktop Publisher. More improvements coming soon. Thanks for using FlowPaper!
