Khaki's Beauty review for Point of Sale

Changed my pin to log in to Shopify settings, pos, but now I can't get into my pos go. What's going on? It's as if the Shopify settings don't connect to Shopify pos go. The Shopify pos for my iPhone doesn't work either. I log in then it asks me for the location and when I add the location and try to continue nothing happens. The screen doesn't move forward or backward. Left wondering, why am I spending and losing so much money with this company.
