Hi, @passy and @frannois I am facing the same issue after upgrading it to “react-native”: “^0.62.2” It works in debug but in a release, it shows same as mentioned by @frannois. After Commenting on a flipper class while creating a build but when I use debug I have to uncomment to use a flipper. It is a wrong practice to comment and uncomment code. Kindly Suggest any solution for this.

@frannois It sounds like you’ve declared Flipper as a debugImplementation dependency. If you do this, you cannot reference any Flipper code in your release builds. This is by design as Flipper code should never be bundled into your production builds.
