When you create a gallery each gallery has it own url, you can view the gallery just by clicking the view gallery button.
The sort-code is to just to display the images if you want to display them within other content type (posts). You can view the sort-code guide here
Can you also provide a link to your site to see if there is an issue, and what other plugins are you using?
Albums and tags work just like “categories” and “tags” for post, and these are optional.
Also check if you are creating secure galleries, secure galleries will not display on the store page unless you change the sort-code.
