My first app with React Native to the Apple App Store has been rejected because they say, "... it contains hidden features, hidden features. Specifically, your app includes support for Hot Update functionality that allows your app to download a new main.jsbundle anytime. It would be appropriate to remove this functionality from your app."
It's a fairly simple app with a search to Firebase Realtime database for jobs.
I've spent hours scouring the net for answers, have about 4 Case numbers with Apple requesting specific information as to exactly where it sees the problem - still waiting.
Has anyone encountered and solved this problem? Detailed message from Apple below.
Guideline 2.3.1 - Performance
We discovered that your app contains hidden features.
Specifically, your app includes support for Hot Update functionality that allows your app to download a new main.jsbundle anytime. It would be appropriate to remove this functionality from your app.

Guideline 2.5.2 - Performance - Software Requirements
Your app, extension, or linked framework appears to contain code designed explicitly with the capability to change your app’s behavior or functionality after App Review approval, which is not in compliance with App Store Review Guideline 2.5.2 and section 3.3.2 of the Apple Developer Program License Agreement.
This code, combined with a remote resource, can facilitate significant changes to your app’s behavior compared to when it was initially reviewed for the App Store. While you may not be using this functionality currently, it has the potential to load private frameworks, private methods, and enable future feature changes. This includes any code which passes arbitrary parameters to dynamic methods such as dlopen(), dlsym(), respondsToSelector:, performSelector:, method_exchangeImplementations(), and running remote scripts in order to change app behavior and/or call SPI, based on the contents of the downloaded script. Even if the remote resource is not intentionally malicious, it could easily be hijacked via a Man In The Middle (MiTM) attack, which can pose a serious security vulnerability to users of your app.
