How Can I download Premium templates?
Premium templates are those that appear when you click “New Design” when starting a new project. No need to download and install. They are already available by default. In version 5.6.4 there are 13 templates, in addition to the “Blank” template.
As @carliedu stated the templates available are included within the purchased app itself.
The clarify further I think “Clean Sky” & “Material Portfolio” seem to be the only two true premium templates that require BSS as seen through the corresponding Epic BootStrap site. The rest which are included actually are all free through Start Bootstrap I believe. Of course all of them have been directly integrated within the BSS app so you don’t need to use custom code, etc., for bringing in a template / partials (which can get messy quick as that is not Bootstrap Studio’s intention).
