As noted in this documentation and confirmed by support, JO analytics can take up to 24 hours to display any email metric results. This is not noted anywhere in the UI of the product and would be an easy way to avoid confusion when the results do not appear right away after publishing a program.
As an admin, it would save me time by having information like this available within the UI. There is an option to “refresh” results within the program analytics, but there is no note present so it just looks like either the program didn’t work, or didn't produce results.
This “quick fix” would help admins decrease time they need to spend debugging or searching for an answer.
