Hi @jamiemccardle, thanks for flagging this (and happy Friday)!
I synced with @AndyK and @ChadB. If your user has already tried clearing cookies and using a different browser (common solves), and is still having this issue, please create a ticket and we'll investigate. Much appreciated!
Thank You! @BlakeH. I created a case, 00380479. The odd thing is that it happens even when I am impersonating the user, but my and other accounts I impersonate are fine. So multiple devices, multiple browsers, and we cleared the cache and cookies in all browsers on all devices.
