Expo FaceDetector is not working

Please provide the following:

  1. SDK Version: 37
  2. Platforms(Android/iOS/web/all): Ios

I am currently using expo camera (8.2.0) and expo-face-detector (8.1.0) and the faceDetection works perfectly when I run my app locally using the expo app. However, the faceDetection does not seem to work when I released the app on testFlight. It does not crash, but rather just seems to not work. I am currently using expo cli to do everything. Does anyone have any ideas?
