But heres the thing, they wouldn't be just training them just a few days ago.
Odds are, they started giving the ride operations teams the proper training that'd be weeks to make sure that it works out. The issue I can see is that the Technology at times, doesn't want to play nice; and as so, it causes ride glitches and technical difficulties common. Especially considering that this is all new technology for Universal, its not just the TM's fault.
