When I click on either the “Create Account” or “Login” button from the rewards popup, it just refreshes my screen. Why is that?
This is occurring because your store account is not enabled through your platform.
We recommend using store accounts regardless -- the feature allows your customers to view their order history, provide you with their email address so you can market to them, etc. It just also happens to be what we use to track each customer's unique rewards account.
To enable store accounts through Shopify, just head over to your Shopify account, click "Settings", "Checkout", and then we'd recommend setting the "Customer Accounts" button to "Accounts are optional."
