Shakúff review for ACF: Metafields Custom Fields

We have been getting "ourstore.myshopify.com refused to connect" the past 2 weeks anytime we try to open the app. I've left two support tickets, no one has got back to me. And when I try to create an account on their portal to see the tickets, it says I'm not allowed on the portal. Then when I tried contacting them on their general site's form, after form submission it says "the site can't be reached". Is this app now dead? What is going on? I'll happily update this review if you guys actually get back to me and help us get the app running again. Please assist!
