I’ve noticed this. Most times I’ve noticed people circling above airports I’ve seen their activity status is literally a few minutes, which with the experience of not waking up to alarms myself a lot over the years, I know what I dont just leave my device if I wake up to my flight overhead at my destination. I don’t generally take screenshots of people circling past their destination at cruise, these were both just friends I managed to capture, both yesterday and when Manila was featured the other week.
I highly imagine this user wasn’t at their device whilst they were circling. I could ask them if needed.
Also do the minutes away start after 2 minutes of activity, or from the last moment the screen was touched? This user was definitely not at their device at this moment in time. Unless there is a maximum amount of hours the simulator can display? Most I’ve seen is 2 hours to my memory.
