My name is Lilith, I'm on the Social Care team at Shopify.
I'd be happy to take a look at your account here. Can you let me know if you've had our support team extend that trial for you already? If not, I can send over an email to your private inbox and we can get that sorted for you.
Let me know how you do with the information above!
Can you share a screenshot of what you see when clicking this link?
Can you let me know what web browser you are using as well? Thanks!
