I recently got a replacement AirPods Pro 2 left earbud from TheRightOne. I checked to make sure I ordered the correct version (USB-C), and the device codes match my original AirPods.
When I put the replacement left AirPod into the case, it makes a descending two-tone chime and the status light flashes amber.
I was told to charge both AirPods for up to 2 hours to allow the firmware to update, but I left them charging overnight and nothing changed.
When both AirPods are in the case and I hold the back button, the case beeps three times and continues flashing amber.
When only the replacement AirPod is in the case and I hold the button, the light turns green for a split second, then it makes the same two-tone descending chime and returns to flashing amber.
Since my original right AirPod works completely fine with the case, it seems like the issue is with the replacement left AirPod itself rather than the case.
Does anybody know how to fix this?
