(I’m not a native speaker of English, so if you can’t understand some part then ask me for rephrasing.)
I used Google login to create my account in gitlab.gnome.org then my name was synced from Google so automatically set and locked. But I wanted to change my name so I set my password and connected to GitLab account and disconnected Google but nothing changes.
By the design is the value set once by Google account sync unable to change forever? Or is it a bug of GitLab?
