Hi Devs, please assist with resolving Cors Policy errors. I'm retrying to send requests to a CRM server running on IIS but they are blocked by CORS Policy (see attached). I am able to send the requests from Postman but I can't from a web app. I am aware that I need to set CORS Policy headers on the server-side, I have done so (see attached).
