Why is the 1 second time-lapse camera in the upper left corner of Apple's mobile phone camera missing?

The system was deleted after the update.

First, we open the camera button on the home page, and then see the small clock button on it. After clicking the button, you can see the set delay time, 3s and 10s. We can choose one according to the specific situation and press the shoot button. After waiting for a period of time, the photo will be taken automatically, then the flash will flash and wait, and finally the shooting is completed.
