I recently edited a question to format it more nicely, and edited its top two answers to make them more standard by our modern community consensuses and practices.
Then, I edited the tour page question, and the preview when asking me to confirm my choice showed the new info.
However, on the tour page itself, it shows an earlier revision of the question, which has a large amount of important detail chopped off, and the earlier revisions of the answers, which go by outdated practices.
Will this eventually update on its own? If the question or its answers are edited again after selecting for the tour page, will the tour page update? If neither of these happens, how long after editing the posts themselves do I need to wait before I select the tour page question?
