Hi. Sure. Most updated versions do work with Angular 16. But in my article I mentioned that the affected project is pretty tied up to some old versions of those libraries.
Not the ideal nor happy situation, we all know that a nicely developed projects should always keep all dependencies up to date, but sad truth is that time to market end turning into technical debt.
Updating ng-bootstrap or any other library with a high level of coupling in this project, will certainly break many components.
