Unable to Login to iCloud on iOS devices

Cx was unable to login to their cloud account when the policy was pushed on to their device. However, when no policy was pushed cx could login. The issue is with applying whitelist configuration to device with passcode turned on..while whitelisting the app some system bundle identifier is getting blocked, we tried whitelisting all system app available for ios and couldn't find a solution

See this support article for a solution.
