@kronenthaler Thanks for the PR! I see you checked

I see several green ci/circleci builds in the "All checks have passed" section of my PR (connect CircleCI to GitHub if not)

but I don't see that the ci/circleci builds have ran — can you please double check you're signed into CircleCI with your GitHub credentials and try pushing another commit?

[kronenthaler]

@getaaron done, the build seems to report one single check, but the pipeline in circleci has multiple steps.
