Why didn't the privacy appear on the home page after it was made public?

Network problems. The reasons why private chat is not displayed after it is made public may be that it can't see your chat due to space settings, system update or buffering, browser problems, network speed and friend settings, or your settings make it impossible to see your chat, the space is reported by users due to poisoning, the system is dynamically released, and the network crashes, which makes it temporarily impossible to view it.
