Hi I have just purchased v4 and again no components but in BSB and other versions of RSD there were components for Bootstrap such as cards, carosel, hero section, nav..... etc...... where have all these gone the library is empty!!!!

As I'm saying in a post a bit earlier in this thread, you need to make your own, or use what others have done before you. In my sharing folder I have collected some bits and bobs to be used by whoever likes them and find them useful. I have navs, carousels, cards, but no hero sections at the time being. You find the URL in my signature.

Why are components available in v2.5 and bootstrap builder though ???

Phil, I'm not able to answer that, I don't work at CC. But my guess is, that components were added to help people get started with the new app. You can still use the components made for RSD 2.5.
