STEPS TO REPRODUCE Install the application “Dynamic-Lyrics" develop by me, which the bundle ID is com.bing.lyrics (https://apps.apple.com/us/app/id6476125287)
Use this APP for a period of time
Go to Settings - Screen Time - See All App & Website Activity
I found that the name and icon displayed in Screen Time are incorrect.
The expectation is: “Dynamic-Lyrics", but the actual display is "com.microsoft.bing"
The guess is that the bundle ID contains the characters com.bing (bing is my name) and is incorrectly recognized as microsoft’s app.
