Search in Spotlight doesn't work on iPhone 12 Pro Max running iOS 18.4.1
On iOS 18.4.1, Spotlight search is not working correctly. Some apps can be found, but others don’t appear in the search results — even though they are installed on the phone. However, if I swipe left to the App Library, I can find those same apps through the search there. This issue didn’t exist before. How can I fix it?
