Weird one. A couple of months ago, my AirPods Pro case stopped charging wirelessly. It charges fine when plugged in. The odd thing is that the software thinks the case is charging when it is not. See the following screenshot: The case is not plugged in and not on wireless charging pad.
I tried resetting the airpods per Apple’s instructions. No change. They are about a year and a few months old. And yeah, this started a month or two after the warranty expired.
