Steps to reproduce
This issue appeared this week for the first time. It is currently affecting hundreds of our users.
As far as we can tell, it looks like Windows Defender Smartscreen is silently blocking file downloads from AWS S3. It appears not all file types are affected, for instance .xlsx, png and .txt files work, but not .pdf.
Turning off SmartScreen immediately resolves the issue, but we can’t suggest this to all of our users.
To reproduce, simply open Edge (v40.15063.0.0) and put this in the address: https://s3.amazonaws.com/construire-dev/temp/test.pdf
