Andrei,
In all likelihood, you got what you paid for: The Boot Camp for the current exam, which does not change until July. While the Exam Content Outline has been out for a while, training providers may not have updated their material to the new ECO by the time your enrolled in the course.
They didn't really "ignore the 2026 changes" - they did not include them because they are not yet applicable to the exam. Many boot camp participants will be taking the exam shortly after the course and not waiting until July.
