The synergy between the ride and the movie is pretty bad, to the point of "not sure how it could have been worse." The ride prominently feature the villains Kylo Ren and General Hux. But the newly released movie reveals that Kylo Ren leaves the Dark Side in the end (even sacrificing his life for the hero), and Hux dies a mole for the Resistance. I think these developments undermine the ride story a little, since if you've seen the movies, you learn that the baddies you encounter during the ride really aren't that bad in the end. And with the ubiquity of Star Wars, most people who'd ride the ride would at least be passingly familiar with how the story goes.
Kylo Ren and Hux were both really weak villains in a poorly planned trilogy, the legacy of which has already been written while the ride has barely opened. The film trilogy of the ride's setting will probably be remembered more for the tug-of-war between two directors and the lack of a coherent idea than for its actual story, which is bad enough in itself. But if Disney wants the ride to be relevant even a few years down the line, they have to continue marketing the trilogy, even though they come with the twists in Episode IX that contradict the idea of the ride.
It just goes to show why there should have been a plan for this trilogy from the get-go. The main actions, character developments, and legacies of the characters in the ride should have been written in stone before the ride was conceptualized (this would have made the movies less internally conflicting as well). As it currently goes, the ride's main antagonists are both people who betray the First Order in the end, lose just about every confrontation they have with the heroes along the way, while the real villain(s) of the trilogy are nowhere to be seen. It's a beautiful ride, well-designed and technologically impressive, but its narrative lacks coherence with the source material - which is only to be expected, since it was designed before the source material was even finished, and the source material itself lacked coherence as well.
What I'm saying is, it looks great, but the overall picture is a mess.
