Failing to get to the Grant Screen of a store

I’m following the steps in the guide for a non-embedded app install, I use the oauth method to redirect to the shopify store with the clientid and scopes set. The client follows the 307, the user is prompted to log into their store if they are not already but it takes them directly the /admin page of the store. I’m expecting the user to see the grant screen and then the callback url being called so that I can I request the token.

The code I have worked before January and I cannot see any material changes that would affect this. Any suggestion on how to troubleshoot this appreciated.

Example 307 (changed id)
https://myteststore.myshopify.com/admin/oauth/authorize?client_id=xxxxxx165daefc7b2ef4b954532xxx&scope=read_products%2Cwrite_products%2Cread_orders%2Cwrite_orders&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fapi%2Fshopify%2Fcallback%3Freturn_to_settings%3Dtrue&state=b9823dc512f2a389ea5900b307e46534

The guide I’m following.
