User Profile

I have developed an app in Flutter and deployed iOS version in TestFlight. App works fine sometimes but on load, app freezes and user need to close the app many times. It works 1 out of 5 times. When i connect my device directly to my mac and run the app, it works fine. This problem is only on iOS and only on the app I downloaded from Testflight. I don't see any issues in the logs as well. App freezes on launch and no action works on the app. If I close it and reopen again, it works sometimes. My backend is NodeJS service hosted on AWS. The REST endpoint is not https but http. Not sure if this is causing the issue or some internal flutter or iOS process which is causing app to freeze. Same app in Android works perfectly fine.
