What this video covers
This video shows how to give signed-in members their own version of a page: make a members template in your Shopify theme, add a Member-Exclusive Page Templates perk to a plan, set each of its options (page type, template, URL path and Path Match Type), and compare what a member and a visitor see on your store.
In short
Make the template first: Online Store > Edit theme > template picker > Create template. Don't assign it to any product, or everyone will see it. If you ever delete it from your theme, delete the perk first.
In Plans & Perks > Membership Perks, add a Member-Exclusive Page Templates perk, then choose the page type and your template (not the standard one).
Enter a page path, or several separated by commas, or leave it empty for every page of that type. Then choose Contains or Exact.
Members see the template only when they're signed in, and the Appstle Memberships app embed must be on. Members on a free trial see it only if Allow membership perks during trial is on in Shop Settings. After you save, your store can take a few minutes to show it.
The template changes how a page looks. To lock a page, use Exclusive Member Content.
