Hi ! I am trying out auth for my school project for its good and feasible auth system. BTW I am using a SPA with react using the SDK provided in the tutorials by auth0.
I am using social auth logins - google, facebook and ms.
However, since yesterday I keep on getting this cors error that is driving me mad :sob:
