Hi
Thank you for your response, justin_900.
My Find My network setting was enabled. A restart and update to the latest software (I was missing the latest update) did not help with the location of the AirPods.
Luckily, my AirPods have been returned to me, but it was only be removing the pairing to my account and phone and then reconnecting them that I got them to update their last known location. I checked the Apple Support page, and reckoned that getting an alert when leaving my AirPods behind in new location would be helpful, but unfortunately I for some reason don't have that option when I
1. Open the Find My app.
2. Go to the Devices tab, and choose your AirPods.
3. Under Notifications, tap Notify When Left Behind.
4. Turn on Notify When Left Behind.
Maybe this is just a US feature?
Anywho, as mentioned my AirPods have been returned to me, but I would still like to know if Find My ever actually updates the location of my connected devices, so that I can use it to find the AirPods if I lose them again, or just not bother with the disappointment.
Sorry for the snark, and thank you for trying to help - it's just so very annoying when something doesn't seem to work and I can't even figure out why.
