I hate how requests that work fine for weeks suddenly stop working and giving stupid responses. Then I figure out a variation of the request that works for a while, then it too stops working eventually. It’s so infuriating.
Just in the last few days, it stopped being able to stop alarms ringing on my partner’s iPhone. She annoyingly insists on using countless alarms throughout the day as reminders, and having Siri able to stop them was useful if she left her phone in another room.
