Find My not showing locations, just says "No Location Found"

To use Find My and Location Services on an iPhone effectively, both your iPhone and the device you're trying to locate must have an active internet connection. These services rely on internet access to share your location with friends and family and to track the locations of devices, people, and items. Without internet connectivity on either end, the sharing and locating features of Find My and Location Services will not function properly.

If you connect to Wifi, doesn't necessarily mean you are connected to the internet. --> Internet not available WiFi and Cellular … - Apple Community

That’s odd. can’t the phones be put into airplane mode from the Lock Screen, though? Besides I was under the impression it would continue to display where it had been detected last. Until the signal returns.

Alright, when it does have internet and there’s no reason it shouldn’t show up, is there any reason why it wouldn’t be showing up?
