I'm Miles from the Social Care team at Shopify. Thanks so much for reaching out.
It looks like we may need to look a bit deeper into this for you, so I have sent you an email with some questions. If you could please reply to that email, I'll be able to move forward to help you out.
In the interim, it's great to hear you've already managed to set up your PayPal account. You're certainly on your way to making some sales. If you're new to Shopify (or even if you're not), I'd recommend checking out Shopify Compass (https://bit.ly/2LyfedE). Shopify Compass is a free program that provides you with webinars and courses on things like store design, marketing and more. It was launched earlier this year and has been a success for lots of merchants.
I look forward to hearing back from you.
