See screenshot. The image is correct, and I am logged into as myself. But the name and other stuff belongs to another user.
Hey @Blondal - this looks like the rules you might have setup on your Single Record page
As you can always tell who you are logged in as in the bottom left corner (when using the sidenav) or the top right corner when using the top-nav.
Even if it worked fine until just suddenly now?
As mentioned in Slack, it looks like this might be related to user list syncing instead.
