I try to use Darwin Notification Center to pass data. But userInfo was ignored. I already to try to use CFNotificationCenterGetDistributedCenter() It can't communicate between System Extension and APP

As the title the enterprise app installation on some iPhone getting weird installation behaviors. (Or there are some things that I didn't understand.) iPhone 6s Plus , iOS 14.2 with LTE or WIFI try to install same app is OK. iPhone 11 Pro, iOS 14.2 with LTE try to install same app is not Good. The enterprise app installation only with WIFI can be completed. I need an explanation.

Until iOS 14.4, My Enterprise App can be download and installed normally. But after a iPhone that upgrade to 14.5 or later, It can't install the Enterprise App. The Error Message like this Unable To Install "My APP" Please try again later. And underlying error in console like this: default 13:04:44.961180+0900 installd Failed to retrieve the IO service matching the device node for <private>. default 13:04:44.961802+0900 installd Failed to retrieve the IO service matching the device node for <private>. default 13:04:44.962209+0900 installd +[DIAttachedDeviceInfo copyImageURLFromDevice:error:]: <~~~> default 13:04:44.962342+0900 installd +[DIAttachedDeviceInfo copyImageURLFromDevice:error:]: <~~~> default 13:04:44.963551+0900 installcoordinationd -[IXSClientConnection _remote_prioritizeCoordinatorForAppWithBundleID:completion:]: No coordinator found for <My app bundle id> and app is not vendable by App Store or is a hard error (1) so showing alert. default 13:04:44.963618+0900 installcoordinationd -[IXSErrorPresenter presentErrorForBundleIDs:code:underlyingError:errorSource:]: Asked to present alert for error 1 source App Store underlying error Error Domain=NSURLErrorDomain Code=-999 "Canceled" UserInfo={NSErrorFailingURLStringKey=https://<the server ip:port>/down/client/ipa, NSErrorFailingURLKey=https://<the server ip:port>down/client/ipa, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <93E0FA8C-059B-4C9C-8901-DD840192E5F9>.<1>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <93E0FA8C-059B-4C9C-8901-DD840192E5F9>.<1>, NSLocalizedDescription=Canceled} for bundle IDs ( "<My app bundle id>" ) I have no idea to solve this problem, because there is less documentation about the OTA installation for Enterprise App. Please Help.
