Store Connect for Shopify

I’ve been working on my Shopify store for the few years. I first I downloaded the app but I didn’t pay for a subscription and tried to connect my Shopify store and I got and error message saying, invalid store domain. I recently paid for a monthly subscription for $6.49. I tried to connect my Shopify store and I keep on getting the same error message. I email the app and got no reply. I deleted the app and tried again to connect my store and I got the same error message. Can SOMEONE please explain what’s going on?

It’s been 3 weeks and thanks to store connect our video game store is doing great people are coming to us instead of GameStop and their saving more money than paying an arm and leg. Thank you Store connect for helping us find a easier option. We would love to see more video game products in the near future as we are a video game store thanks 💚🎮👨🏻‍💻

This made everything easy for me as a starter, I was able to drop ship products right from other stores. Definitely a A+
