I am using postman 6.1.3 and mac os 10.13.4.
My login request return a cookie and postman set it to cookies I can see that cookie in postman cookies part. But all the requests after login not add that cookie . Can postman manage all cookies?
I ran across your post while searching for an issue with cookies since last Postman update. Hope this might help: https://github.com/postmanlabs/postman-app-support/issues/4581
