<Error>: Couldn't read values in CFPrefsPlistSource

Hi,


I'm facing some problemas with ios 11. We use App Groups to share some information between some of our apps, but some clients after updated their iPhone to iOS 11+ the apps stoped accessing the information in the App Groups. I'm getting following error:


<Error>: Couldn't read values in CFPrefsPlistSource<0x1c010b5b0> (Domain: group.com.****, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd


Anyone has any idea of what can be causing this? Some clients after delete all apps and install again resolved the problem, but some said that it didn't resolved (I don't know if they really deleted all of our apps).


There is some way to recycle or clean the App Groups?


Thanks in advance
