I'm still early in the game, but I stopped for a few minutes to finish up the Augmented Reality Training challenges. Completing the first set of them earned me a new gadget.
However, a bunch more "Advanced" challenges unlocked, and I'm absolutely terrible at them. I've considered just leaving them for now, and coming back when I have more experience, but I'm worried that perhaps something useful will unlock if I can finish them off now.
Is there any reason to finish up these challenges now, or can I safely move on with the game?
