For people who use multiple Facebook accounts, sometimes you are in the wrong one when you log in to CrowdTangle. Then CrowdTangle seems to get stuck on the bad version of you, and not let you switch to the good version of you.
Fear not, it's not a big deal; you just have to follow this pattern:
Go to Facebook and log out of Bad You. 😡
Go back to Facebook and log in to Good You. 😀
Go to https://apps.crowdtangle.com/logout to log out of CrowdTangle. This will erase your CrowdTangle session with Bad You 👻 and take you to crowdtangle.com.
Go back to your dashboard (or click "Log In" to go to https://apps.crowdtangle.com and see your available dashboards). You should find yourself back in the dashboard as Good You. 🙃
