Ruby and Shopify CLI both installed fresh via Brew. Ngrok is setup and authenticated locally.
After serving the demo app if I follow the ngrok link I hit the classic Oauth error invalid_request: The redirect_uri is not whitelisted. Reproduced error in chrome, safari, chrome incognito and safari private browsing and also chrome/safari on iOS.
What do I need to do to get the demo app to work? The redirect URI is automatically whitelisted in app configuration settings and looks correct, yet I keep running into this error.
