I saw the error right on my main repo dashboard. Clicking on the error just caused some manual “fix” where it found the commit, where the actual fix was found by going into a specific commit (before it was “fixed”) and noting the message at the top, which mentioned a help page which then told me that I needed the app. The error message at the front page should probably link to somewhere more useful, though I’m not sure how it could both fix and provide info as to the issue at the same time.
I didn’t install the app because it seemed like its only purpose was to give Codecov access to reply to PRs with coverage info; something I don’t currently want. It wasn’t clear that I wouldn’t be able to get any information at all without the app. Coming from coveralls, the need for this extra app confuses me. When I upload the report, the upload should have everything needed to link back to a commit, as far as I can tell.
