Chrome --disable-web-security no longer works

Question

We have been using the following to open Google Crome without a Cross-Origin limitation for debug purposes for some time. Yesterday it stopped working on all of our Windows computers.

chrome.exe https://"www.testsite.com" --disable-web-security --user-data-dir="d:/tempchromedata"

Current version of Chrome is Version 70.0.3538.77 (Official Build) (64-bit)

Answer 1
