Snaps Theme Portfolio Template is missing in the Page Attributes section

ISSUE 1:
Upon installing the SNAPS THEME on MoodeeCactusRecords.com, I wanted to create the Portfolio they have on their DEMO PAGE on my Homepage. Their instructions say to
1. Create a new page.
2. Assign the Portfolio Page Template from the Page Attributes section.
3. Go to Customizer > Static Front Page and choose the new page as my site’s static Front Page.

But in #2, in my new page and going to Page Attributes, there is only a dropdown box that has options for: “Parent Page:” and selections only for: Sample Page, Welcome!, Shop, Contact, Blog, etc. and a section that says “Order”.

There is no option to assign the Portfolio Page Template.

Next, upon googling for tireless hours I only found a few things to try.

I had my (published) homepage static, then not static. That did not help. I saw in one forum the SNAPS THEME Demo page is set as static homepage; so I changed it back to static.

ISSUE 2:
I do not see a “Template Options” tab on the left panel of my Dashboard (as I read in one forum). The Appearance section gives me no option for assistance in the missing “Portfolio Page Template”.

ISSUE 3:
In trying to follow steps from this post:
https://wordpress.com/support/portfolios/

It says:
“Activating a Portfolio and Setting Portfolio Projects Per Page
If your theme doesn’t have the Portfolio feature active by default, you can turn it on by going to My Sites → Manage → Settings → Writing → Content Types and turning on the “Portfolio Projects” option.”

But my dashboard under Settings > Writing there is no “Content Types”. There is a Default Post Format that includes “Standard, Aside, Chat, Gallery, Link, Image, Quote, Status, Video, Audio. There is nothing on this page to turn on “Portfolio Projects”.

(Please excuse the mess as I am just setting the pages up without actual content.)
