airpods pro Popup shows up even though the AirPods case is closed

Hi Crismexes,

Thanks for using Apple Support Communities. If you haven't already done so, try resetting your AirPods and see if this persists. See how here:

1. Put your AirPods in their charging case, and close the lid.
2. Wait 30 seconds.
3. Open the lid of your charging case.
4. On your iPhone, iPad, or iPod touch, go to Settings > Bluetooth and tap the More Info button  next to your AirPods. (If you don't see your AirPods in Settings > Bluetooth, just go to the next step.)
5. Tap Forget This Device, and tap again to confirm.
6. With the lid open, press and hold the setup button on the back of the case for about 15 seconds, until the status light flashes amber, then white.*
7. 
8. Reconnect your AirPods: With your AirPods in their charging case and the lid open, place your AirPods close to your iPhone, iPad, or iPod touch. Follow the steps on your device's screen.
