I’m running into the same problem. In my normal browser window where I’m logged into GitHub and Codecov, I can see the pages linked in the Codecov comment in a pull request. If I use a private browser window and paste the links in, I run into the 403 Forbidden error.
@tom any clues? Is this the expected behavior? As in, is it a requirement to log in to Codecov before viewing any some of the reports?
