Defunct/No longer working – WhenToPost: Best Times to Post Review

After connecting to Instagram, it throws this error: {"error_type": "OAuthException", "code": 400, "error_message": "Invalid scope field(s): comments,likes"} Website for App support doesn't resolve either. Makes me think this app has been abandoned and needs to be removed from the App store if it's no longer being updated.
