Hi @Emma ,
Welcome to our forum!
According to your description, i notice that you case is more related to Viva Engage. Based on my research, i found that if you have already updated the name in admin settings but it hasn’t been updated on the Viva Engage app, you may want to try clearing your browser cache and cookies or try accessing the app from a different browser.
If it doesn't help, it's suggested that you could post your case in dedicated forum for Viva Engage for more professional help.
