I can go to https://account.microsoft.com and log in successfully and visit other Microsoft sites like outlook.com. However, when I go to bing.com it shows "Sign in" and when clicked I am briefly taken to login.live.com and then back to bing.com without actually being logged in. I have tried restarting with add-ons disabled, content blocking setting is at Standard. I have cleared cookies/web data and tried adding both URLs to Exceptions Cookies and Site Data. However, nothing seems to work.
