I just got some Airpods Pro for my Birthday today and noticed that when the case is closed and charging, the Airpod and Airpod case indicators will show on the battery widget on my phone for a few seconds then disappear. It doesn't show as connected when I check my bluetooth settings. But when I open the case, it immediately shows up and the Airpods automatically connect back to the phone. Is this expected behavior? I thought I would be able to monitor the charging status of the case and Airpods while they were on the charger.
