I was going through James Duffy’s profile and was unable to scroll through his pinned projects. Seems like the “stuck” one is the same as the last one that actually works. And when visiting his profile from computer it seems like there are only two pinned projects so I have no idea from where that third stuck one is coming from.
Here is his profile:
I didn’t notice this issue on any other profile. I am running iOS 14.5.1 on iPhone 8 Plus and the latest version of the GitHub app.
