I have an original series 0 watch. I know I'm going to have to upgrade it sometime, but with rumours of a new case this fall, I'm inclined to wait. It actually works fine for what I do, which is part of why I'm in no real rush to upgrade. But... it no longer responds to Siri requests. I push the button, get the Siri input graphics, and every time get told that it couldn't understand what I was saying. I'm wondering if something is wrong with the microphone. Anyone else run into a problem like this? It's doubtful that it's worth the cost of the repair.
