Chrome not downloading PDFs on Marshmallow I migrated from a Nexus 5 to a Nexus 5X using "Set up nearby device". On the Nexus 5 when I visit turtletrader.com/pdfs/babe-ruth.pdf in Chrome it offers to download the PDF. On the Nexus 5X it doesn't do anything.
I was able to fix this by the following:


Go to Settings
Select Apps
Select Chrome
Clicking Disable
Enabling again


Then when I try to download a PDF it asked for permission to access the folder. 

As pointed out in the comments a better fix is:


Go to Settings
Select Apps
Select Chrome
Select Permissions
Enable Storage permission
