Dynamic Island suddenly disappeared?

① Currently, the system restricts Dynamic Island to only support 8-12 hours of storage in the background, which can be recovered by entering App again after disappearing.
② If multiple Dynamic Islands are opened at the same time, our Dynamic Islands may be hidden and can be recovered by sliding them left and right.
③ If it still can't be displayed, you can go to the Dynamic Island page and reset it.
④Restart your mobile phone and try again if it still does not work;
