I was using cloak tracker but hardly ever see any 'glow' about the enemy. dont know if thats how its supposed to be or if its a bug like it isn't alway on.
i switched to tracker (footprints) but i haven't seen a footprint yet and i've actually followed directly behind an enemy.
seems like one of those "i bought it but it didn't actually unlock" bugs.
Cloak tracker only works if people enter into stealth mode in your vicinity, it does not detect stealth mode if someone enters it from far away. Tracker works for me, do you see the glowing triangles?
