Why Does the App Information Center Receive a Low Food Alert, but the Page Still Shows Sufficient Food Remaining?

When the remaining food is in a critical state, the machine will report a food shortage and immediately send an alert message. However, during the rotation of the machine, some food may block the sensor again, resulting in the page still showing that there is sufficient remaining food.
The food barrel itself is transparent, and you can see the general situation of the remaining food. If you receive a food shortage alert, just add food.
