Smarter kettle v3

To anyone who owns one of the above by Smarter am, have they lost control of it via the app? App and any of the automations I had set up no longer work. Deleted the app , successfully re added the kettle but still have no control over the functionality of the kettle through the app. Contacted support and they are supposedly working on an issue . Been a week. In saying that the app should work locally ? Anyone know if their service is shutting down? Cheers
