Siri
When I asked Siri what the volume is on my iPhone 12 this morning, as I have many times, her response was "Sorry, there was a problem determining volume." And, an alarm she set last night didn't go off this morning. I was awake already when it should have gone off.
I checked the alarm just now, with her setting it, and it worked fine. But the problem determining volume is still present. This morning was the first time that ever happened. Appreciate any help. Thanks.
