I am working on a new app and am installing it manually by typing the URL into my web browser. This is properly bringing me to my Shopify store and is displaying the permissions screen as desired; however, when I click the 'Install app' button, I receive a page that says there is an Untrusted Connection. The URL in the browser reads:
https://.myshopify.com.myshopify.com/admin/oauth/authorize?client_id=&scope=read_customers,write_orders&redirect_uri=;
Note that the myshopify.com portion of the URL is repeated twice and the user is not sent to the redirect URI I specified.
What could be going wrong here? How can I fix this issue? Shopify doesn't really offer much in the form of support. Any help would be appreciated.
