With iOS 14 devices we can see that Many MDM Commands Fails with error " Couldn’t communicate with a helper application." . This Error is more frequent in InstallApplication , InstallProfile command , but other MDM commads also face the same issue. I have attach sample response from some devices. We have seen this error in previous version of iOS but with iOS 14 these are very frequent.
