iOS Crash: Symbol not found, probably Network.framework

Problem Description

We create and use ANE for advertising. We have recently updated several Ad Network SDKs to comply with Apple's Privacy Manifest.

Apps using the new SDK crash when initializing ads.

When I check the crash log, it seems like the error is about missing symbols included in Network.framework. (The real cause may lie somewhere else.)

I also contacted Ad Network and they told me that they had updated the new SDK version to use Network.framework, but they couldn't tell me anything else. Unfortunately, they say AIR is not supported.

Network.framework is specified in linkerOption of ANE's platform.xml. When you check the app information with otool, Network.framework is displayed.

What am I missing? I would appreciate your help.

AIR SDK: 50.2.4.4
Device: iPhone 14 Pro (iOS 17.3.1), iPhone 6 Plus (iOS 12.5.7)
