    not able to replicate on my iPad but I do not have a setup where I could troubleshoot AirPlay.

    My stacktrace is here: https://www.dropbox.com/sh/75y4k27n6epu856/AAA684cpdvhDQxse9ZxvMyGDa?dl=0

    Is anyone able to reproduce this locally?

    More call stacks from seemingly related rejections:

    @BRIGHTONRICH

    Any news on this yet - everyday we lose on this is delaying release...

    Hi @BRIGHTONRICH:

    This seems to be related to the airplay issue, it has resulted with at least 5 rejections from apple with the comment attached "Your app crashed on iPad or iPhone running iOS 11.2.5 connected to an IPv6 network during our review." It does appear that the tester is connecting with airpla:

    2018-03-06 17:12:20.2996 -0800 0x1d16 1024 0x0 342 FrontBoardServices: [FBSScene] [com.ourcompany.ourapp - AirPlay] Created client agent: <UIApplicationSceneClientAgent: 0x13f0f42a0>.

    Every rejection is due to "SPRINGBOARD, scene-create watchdog transgression" (our app was stuck in the initial load for too long).

    The following is the stack trace for thread 0:

    We're looking into this now. Can you post any call stacks please? I'd like to verify that we're all seeing the same issue.

    So far have tried submissions (ALL REJECTED) using

    Unity IOS version 2.0.3 (3) Build with Unity 2017.2.1f1

    Unity IOS version 2.0.5 (1) Build with Unity 2017.3.0p2

    Unity IOS version 2.0.6 (1) Build with Unity 2017.2.0f3

    Unity IOS version 2.0.7 (1) Build with Unity 2017.3.1p4

    @BRIGHTONRICH my game based on version 4.7 has got 4 times rejections from Apple Review because of airplay broken, so i wish you could make a DisplayManager fix that doesn't break airplay.

    Once we upgraded to 2017.1.3p2 to work around this issue which was causing Apple's rejection, we now got another rejection from Apple - this time with this crash reason:

    Termination Description: SPRINGBOARD, scene-create watchdog transgression: com.ourComany.ourApp exhausted real (wall clock) time allowance of 10.00 seconds

    and the crashed thread stack says we were in DisplayLinkItem:update_link, which is called every frame refresh, and then it realized some resource that it needs (SourceList or CFPrefs?) is locked and started waiting for it, and 10sec elapsed while it was waiting.

    This seems to be biting many people with different versions of Unity, once they try to work around the AirPlay issue.
