I still don't understand how the blue outline works if the enemy Yoru uses his ultimate. Does it appear only when he's looking at you (if yes, from any distance?) or if he's close at a certain range?

I've tried restarting my game straight after but they still appear offline until the next time they log on. Which is annoying when I meet good people I wanna duo with in ranked.

Im in malaysia and the closest server available to me is tokyo... Whilst the singaporean server shows for my friends abroad
