We've been using React Native and Expo Go to develop a mobile application, however when building and testing using TestFlight, we run into an unexpected error where the app crashes after interacting with one button but that same button doesn't crash in Expo Go. (To add, we have 2 buttons on a screen, both which do very similar actions but only one crashes in TestFlight.) Below is the error log with some stack traces. Anyone else experience something similar to this?

Not a crash, but with a React Native app it hangs at random places when downloaded from TestFlight, yet the exact same build when installed from the App Store is ok (the app was uploaded to TestFlight, then released to the App Store, then later found the issue in TF). So the exact same build experiences issues when installed from TF but not when installed from the App Store.

@mungbeans , to clarify your response, are you saying that you experienced some sort of hang/error in TestFlight similar to what I have posted above, but when you published it to the App Store, you no longer had those issues? Also what environment were you testing your application in, for our application we used React Native and tested it with Expo Go.
