Answer by myself, We found it was not Notification service extension issue, it was on our push sever stop pushing

@edford, thanks for your patient, I come back to close my thread here, I got it solved on this link: Problem solved

Thanks @edford, I have downloaded Xcode13.3 beta 2, and trying to drag and drop the crash file into Xcode device logs Panel, no luck on my side. it does not accept at all. VCS-2022-02-08-153814.log VCS-2022-02-08-094833.log

I replied by myself, that was because Apple has updated to report Callkit upon Receiving PushKit, Apple restrain from abusing Pushkit for other purpose.

Thanks @edford. My issue is that (my app generated since 2007 by Objective C ) on old iOS (prior to iOS 15.x), I can find the crash file with XXXX.crash or XXXX.ips.beta, and update the name to .crash, download .dsym file to parse the crash file by Xcode, since iOS 15.x, at least on my team side, there is no XXX.crash or xxxx.ips.beta file when crash occurred. attached file was on iOS 15.x device when app was crashed, I have no idea how to take old school way to parse those crash log. if I take the old school to change the extension name from .log to .crash Xcode does not accept those file at all when I drag to device logs panel. Best regards.

Hi adford, I submitted my Feedback too. crash signature are same as above: https://feedbackassistant.apple.com/feedback/9833627 VM - Fault hit memory shortage VM - Compressor failed a blocking pager_get

I get it fixed by download Xcode 13.0 beta 3

I have googled an tried many ways, however, none of them works for me. even I have removed Xcode and re-install, update to latest Mac OS. My OS is Big Sur OS 11.5.1 release Xccode 12.5.1 release. my iPhone format is 00008030-xxxxxxxx, iPhone 11. any suggestion will be much welcome Thanks,

Not sure on item1, However for Item 2. Once you kick off the CallKit for incoming call, on your completion handler, you can add CallAnswerAction to pickup the call, which seems auto-pickup without user consent. If my understanding is correct.
