On desktop/laptop computers it is build 4.27.0 which was released February 22, 2024. To upgrade to the latest version either wait for the automatic update or go to https://preveil.com/download, download the installer and run.
The automatic update is part of a staged rollout plan where app updates gradually increase to the user population following the release date.
The Windows 4.27.0 build has been pulled from the website and replaced with 4.26.0 while we investigate a file download issue.
