Example URL:
https://storage.googleapis.com/ and https://unify.my.salesforce.com/console#

Steps to reproduce the problem:
1. User login to any of the above links 
2. Then open some random case which has some links to download
3. Clicks on link to download the file
4. Shows Failed - Blocked error

If they go to downloads page, they need to click on failed-blocked which then allows them to download. Though users got a workaround, but this is still a concern as download method becomes complicated and the primary issue still exist.

What is the expected behavior?
These files should get downloaded like any other files from internet

What went wrong?
The problems seems to be related to chrome download policy.
