Hello, I am unable to change display name in JITSI it asks display name for first time but if logged out and re join picks display name from browser cache itself. Also there is no option visible to change display name while ongoing meeting.
Welcome to the community!
You can change your display name by clicking on the ellipsis (the three dots) on the toolbar and then selecting “Settings”. Once in the “Settings” pop-up box, click on the “Profile” tab and you’ll be able to change your display name there.
