On iOS16.1 beta. In my widget extension, FileManager.default.url(forUbiquityContainerIdentifier: nil) always return nil. In the previous iOS versions(iOS16.0 iOS16.0.1) it worked. My app is ScriptWidget, after enable iCloud, the widget can not visit scripts in iCloud Documents directory. But the main app and extent worked as before (can visit). I also post a feedback https://feedbackassistant.apple.com/feedback/11529890
