I am trying to add OAuth2 sessions to my app and I have been fighting for a long time. An error keeps on popping.
It is error Error 400: redirect_uri_mismatch.
I don’t know what else to do. I have the client well configured but this uri mismatch is breaking my head.
Summary
The developer is trying to add OAuth2 Google Sign In to their React Native app, but they keep getting a "redirect_uri_mismatch" error. They have already configured the client correctly and are unsure of what to do next.
