"last Online"

A couple ppl in my gang it shows they havnt been on in however many days, but I've spoken to them, so it must be a glitch.

We normally kick out ppl after 7 days.... But since we noticed this we haven't been able to...

We don't want to lose actual active people.

I'm not 100% sure, but I was under the impression that the time listed next to a players name on their gang page was the time of their last GPS ping, not the last time they were in game. So if someone checked 'Hide my location' in their settings, that time wouldn't necessarily be the last time they played.

This shouldn't be the case.

The time indicated is the last time they moved. So if they are playing normally, this value should be updated, even if he has is position hidden

he mentioned that he spoke to them, one thing i have noticed is thta the games notifications seems separate from the game, you can check and see notifications without going into the game. plus even if he did go into game perhaps they never went into map?

Yes this may be it
