Can you provide some context here? Just seeing the message from Apple doesn’t tell us anything about your app. Did you make use of APIs? What type of components did you use (e.g. location sensor, maps, etc.)?
I’m not convinced this is something you caused to happen but it’s still helpful to have more details.
This has some guesses about the problem:
