Can't change templates anymore?

I've used squarespace before, a few years ago, and one of the main reasons I liked it was because I can change templates and try different designs.

I've just subscribed again today & now it seems that feature is gone & there is no way to change templates. I understand it's all one template now, and I could play around with colours and fonts and page layouts until I've achieved another look..... but why? I don't understand how this decision to give end users more work to do is a feature, or am I missing something? I'd much prefer to just click on a different look and see if I like it or not, which was how it used to be before.

Aside from starting a new website with a different template (and then applying for a refund on the old one, another great use of time) is there any way of switching the look of my website?

I'm hoping I've missed something obvious...
