I share my location with a friend and they share their location with me. Currently theirs shows location not found in my friends list.
If they stopped sharing their location, I thought that meant they disappeared out of my friends list?
what exactly does location not found mean?
Also, they have signal and 3G/4g so does no location found mean they have stopped sharing their location with me?
Yes, regardless of their cellular connection type, it would still be possible for them to stop sharing their location with you.
It means, simply, that they cannot be found by the Find My app at that point in time.

If they stopped sharing their location with me would they disappear from my friends list even if I still share my location with them?
What is the difference between stop sharing location and remove friend?
Does no location found mean they have stopped sharing their location with me?
thank you. If they stopped sharing their location with me would they disappear from my friends list even if I still share my location with them?
