ms-identity-javascript-v2: Access to fetch from origin has been blocked by CORS

We;re having a bit of a similar issue as described here. Currently when running the sample code with msal version 1, which uses the implicit grant flow, all works fine. However, when we try to use this sample that uses msal 2 it fails with the following error:

Updating the Azure App Regisrtation to use the “SPA Redirect URI” did not fix it:

We also tried to disable “implicit grant” in the hope that would resolve the CORSS issue but no luck. Is there still something we’re missing here?

@DarkLite1 aah, now I see. The issue seems to be that you have both Web and Single-page application added as platforms. Web is the one causing your CORS issue, you should I ideally have separate registrations for each platform. Try removing Web and its return_uris and see if that solves the issue.
