I just updated to Version 12.0 and suddenly, a contact / user button appears in the upper right Corner, left to the settings button.
(This is not the contacts app!!)
When clicking in that contact-button a list of all users appears that refreshes every second.
-> I found no way to deativate that contact button. I uninstalled almost all apps, but that didn´t help.
Any help please how to hide that button? Or at least not show all users when clicking on it?
