Yesterday, I listened to a podcast with only my right AirPod. The left AirPod was in the case. I then charged both AirPods overnight. This morning, the left AirPod refused to work: no audio, no chime when inserted, and no Siri when double tapping. The right AirPod worked fine. I tried rebooting my iPhone, disconnecting and reconnecting the AirPods, turning off/on Bluetooth and toggling on/off Automatic Ear detection in settings. Nothing worked. After fiddling around I was able to get the left AirPod to work, but then the right AirPod stopped working. And when I checked battery levels, only the battery level for the working AirPod would show. When I tried another Bluetooth headphone, it worked properly. Only the AirPods have this problem. I've used my AirPods for several days and this is the first problem that I have had. Any suggestions?
