How To Fix iPhone Photos Widget Not Working

The best solution for adding content to Photo Widget is to charge your iPhone overnight and see the photo on your iPhone screen in the morning.
The thing is that the application needs to scan your photos in order to add some of them to the "For you" section, which is responsible for displaying photos in the Widget.
And in order not to overload the resources of the iPhone when we use it, the Photos app scans when we sleep.
