OAuth cannot run inside the Shopify admin iframe (that causes “accounts.shopify.com refused to connect”). This page opens the install flow in a top-level browser tab.1) Preferred: open the app from Shopify Admin → Apps → Kwik Subscription (after install).2) Or paste your shop domain below (e.g. kwik-retail.myshopify.com) and continue.3) App URL must be https://ksapp.krezine.cloud. In Partners / Dev Dashboard, never set App URL to accounts.shopify.com or your-store.myshopify.com.4) Still stuck? Admin → Settings → Apps → uninstall Kwik Subscription, then install again from this page.Continue with Shopify
