so I ran BFG, following the instructions here. https://rtyley.github.io/bfg-repo-cleaner/ The console output from BFG looked good but, after pushing, when I got back to github, I could still find the sensitive data in pull requests > clsoed > old merged request > files changed. I've seen talk about github's gc maybe taking some time. Do I have to wait for changes to show up?
EDIT
I overlooked one line in the push output
! [remote rejected] refs/pull/1/head -> refs/pull/1/head (deny updating a hidden ref)
Some of the text that I want to remove is in hidden files. Is that the source?
