Hey, been trying out SuperTokens and got stuck on a CORS issue. In the CORS setting if the origin is https://mydomain.com, I get a cors error when i try to access it from https://dev-myapp1.mydomain.com

You need to add a cors middleware. Please see how to do that in our backend setup. And also you can see a page on cors debugging in the debugging section in our docs.
