Opening a new tab in UpGrade prompts for re-authorization

Solution

In Safari, the default privacy option is to prevent cross-site tracking. This also prevents UpGrade from retaining your session between tabs. Disable the cross-site tracking option by opening your Safari Preferences, navigating to Privacy, and un-checking the Website tracking checkbox. Now you should be able to open experiments in new tabs and remained logged in. If you're using another browser, try resetting your browser's cookie settings and checking that your browser is up-to-date. Firefox and Chrome's default settings should let you retain sessions across tabs. You may also be in Incognito Mode which has additional cookie blocking settings.
