Using Cloud Edition. Signed in as Administrator. Go to Users tab. I click on one of the users. A different user is displayed. No matter which user I click on, the same (wrong) user is displayed.
I cannot reproduce your issue on Cloud Edition so it seems to me like a hardware, OS or browser failure.
Try restarting your device and see if the issue is solved
I am also not able to reproduce your issue on cloud edition. l, in fact, checked every single user I have created. In all cases, the correct user page comes up.
Sorry folks. PEBCAK! My password manager was auto filling MY information every time I opened a user page.
