Nothing is happening when I press and hold the stem on my Airpod Pros 2nd Gen. Anybody else have this issue and fix it easily?

Hi 3spn,

Thanks for reaching out to the community. Take a look at the steps and article below to customize the settings on your AirPods Pro to your preference.

1. "With your AirPods in your ears and connected to your iPhone, iPad, or iPod touch, go to Settings > Bluetooth. Alternatively, you can go to Settings > AirPods.
2. Tap the More Info button next to your AirPods in the list of devices.
3. Under Press and Hold AirPods, tap Left or Right, then make sure that Noise Control is selected.
4. Select the two or three noise control modes that you want to use with press and hold. If both AirPods are set to change noise control modes, a change to the press-and-hold action settings on one AirPod applies to both".
