Create a post page

Hi, I am using customizr and am at a loss.

Before moving to this theme, I had a blog page. This would show my posts on my site.

I now can’t get my blog page to show such things. I have read lots and I realise that one solution would be to make my front page static and chose my post page to be my blog. I also have read a lot about making child themes etc, but that seems so excessive for such a simple task.

My site is https://www.samwildphotography.com

and help would be massively appreciated!
