I have been developing an app for 1.5 years and while doing so, have heavily tested using Test Flight.
I attempted to submit my app for review to release on the app store, but to my surprise, it was rejected. I was a little confused as to why - here is what the reviewer said:
We still discovered one or more bugs in your app. Specifically, we were not able to fully load your app content after launch, your app launch a green blank screen. Please review the details below and complete the next steps.
The only reproduction steps they say to take are to use an iPhone running 15.2 OS and reinstall the app. As I released the app I submitted to Test Flight, all of my testers confirmed the app working as intended.
I have personally run the app on a device that has never run it before running 15.2 and it worked as intended.
I have seen other forum posts mentioning a black, white or clear screen on open, but never a green screen. I am unsure if the application crashes or it just hangs as the reviewer mentions almost nothing in their report, which is not helpful at all.
Does anyone have information as to what the problem could be or something I could try? I can not reproduce this issue and the lack of information provided by Apple is infuriating.
