Hey fonslaudy,
Thanks for using Apple Support Communities. Let's start with the information in the section "Intro to using Find My with AirPods" to ensure everything is set up correctly: Locate AirPods in Find My - Apple Support
Intro to using Find My with AirPods
* You can use Find My with all AirPods models, but some models may have additional features to help you find them. If you’re not sure which AirPods you have, see Which AirPods do I have?
* To locate your AirPods, you must turn on Find My on a paired device (such as your iPhone or Mac) before they’re lost.
* For the best experience with Find My, make sure your paired device has the latest version of iOS, iPadOS, watchOS, or macOS installed.
* You can turn on the Find My network to see the location of some AirPods models even when they’re out of range from your device. If the Find My network is turned off (or if your AirPods don’t support the Find My network), the Find My app shows the last time and place they were connected. See Turn on the Find My network.
* If your AirPods are out of range or need to charge, you might see their last known location, “No location found,” or “Offline” in Find My. If they come back online, you get a notification on devices you paired with them.
If you still don't see your AirPods in the Find My app, reset your AirPods and connect them again. Here's a guide to help, just in case: How to reset your AirPods and AirPods Pro - Apple Support
Let us know how it goes.
Take care!
