Technology and cargo are now completely separate inventories, so any technology you had installed in your general inventory needs to be reinstalled in your technology inventory.
As a way of compensating for this nerf, they also added supercharged slots, which provide a buff to the technology installed in that slot. These are randomly laid out. Higher class equipment has more supercharged slots, but you may need to add slots to uncover all of the supercharged slots.
That sounds really frustrating!
I will say that at endgame, the Hector lecture videos are considered the gold standard for guide videos and tend to be the most commonly used PF strats, and those videos do actually explain the mechanics in detail, with diagrams of how the attacks go out. So while I hope your relationship with your static improves, or you find a better one, once you reach endgame, you should hopefully have a better chance at learning the mechanics either way.
