home app slow to work properly.
when my wife opens the home app on her iPhone all the accessories (lights) say 'updating' and it is 3 or 4 minutes before they can be turned on or off. she is running the latest iOS software and has tried rebooting the phone. the home app on my phone controlling the same household and lights works fine and there is no delay at all. any suggestions or help would be appreciated. many thanks
