Working on a project in Android Studio, and I had a single file that I committed by mistake that was just over github's 100MB limit. I needed to modify that file anyway, so I did so, and it's about 50 MB now.
Problem is, when I try to push the new commit with the smaller file, it's also trying to push the old commit with the file that's too big. How can I skip the older commit and just push the new one?
