Is your instance the same as your email domain? If so, do I have your permission to log in and take a look at how things are setup? Can you please provide me with the feed name and a project+release I can take a look at to see the behavior?
If that’s not okay for security reasons, can you please privately message me the above screenshots? I would need how screenshots of the feed setup, the steps referencing the packages, as well as the pages that are throwing the errors.
