Hello! I am working on the Today Extension project to my iOS App. And I am trying to achieve data sharing between them. I have added the App Groups possibility to App ID's to both projects. I have tried using the NSUserDefaults with the App Group ID, and interestingly I can share the data within a project (either Parent App or Today Extension) this way, but not between them. Am I missing something? Since both projects can use this App Group ID to share data within themselves, how is it not possible to share between them? Should I allow the external access somewhere?
