OwnCloud Problem Shooting

Today, I tried to announce my app cloned and modified from owncloud and I met this problem when I upload to iTunesConnect.

ERROR ITMS-90362:"Invalid Info.plist value. The value for the key 'NSExtensionFilePrviderDocumentGroup' in bundle Owncloud iOs client.app/Plugins/ownCloudExtAppFileProvider.appx is invalid. Values must match values contained in the com.apple.security.application-groups entitlement. The given value 'group.com.owncloud.iOSmobileapp' was not found in the entitlement values:("group.com.yourDomain.OOO")"

How to solve it:
 You need to go to  Extension: ownCloudExtAppFileProvider info.plist and change "NSExtension" -> "NSExtensionFileProviderDocumentGroup" value to "group.com.yourDomain.OOO"
