My scouter wont open when I want to put a chip or just open it when I press U. is this just a glitch?

Chips are gone, hit T to turn on\off your scouter I believe. If you need a scouter buy one from Merchant.

If you played before the scouter patch go into your Wagu Machine cash bank thingy, and there should be a scouter in there for you. It comes with DB mob scan, quest scan etc. Chips have been removed and the best scouter in the game comes from the Aria waterfall in Korin Forest.

Ya scouter doesn't have the chips anymore I was a bit confused on that when I got back into this game as we'll.
