 * I just got a message from a user that the viewer is blocked: Microsoft defender
   smartscreen has blocked this unsafe content.
 * I suppose it’s a similar issue as described here
    [https://wordpress.org/support/topic/got-a-security-defender-warning-on-the-pdf-screen/page/2/](https://wordpress.org/support/topic/got-a-security-defender-warning-on-the-pdf-screen/page/2/)
 * Is there a solution? Otherwise I think this otherwise great plugin can’t be used…

 * Microsoft provides no help with this issue and I’m unsure what it’s complaining
   about. Plus it doesn’t always happen.
