GitHub username change isn't reflected on galaxy

Hi Team,

Currently i am facing issue in repository sync between Galaxy and GitHub.

Initially when i created my Galaxy account using my GitHub account i had username as ‘venkicnu’, but later i changed my GitHub username as ‘bukkasamudram’.

Now when i login Galaxy using GitHub, it still showing my old username under MYCONTENT page.

I tried to revoke access to Galaxy and re-logged in Galaxy, but no luck.

Please help me how to solve this issue.

Thanks in advance
Venkat
