We've got a successful build check that was triggering a failure note as expected. It was fixed in a later commit which triggered a new build.
We're still showing the failed build but it's followed up by multiple successful build and because there is an (ultimately unresolvable without the commit it won't ever contain) failed build for the PR it won't approve the PR.
The note on the Successful Build check is insanity. "If there are more builds than specified above, they are all required to be successful in order to merge the pull request."
This is a great setting but utterly demoralizing to someone who's project fails and they resolve. They can _never_ resolve the PR short of deleting and recreating the PR.
