Silent Auth during Post-Login Action

Get Help
1

I’m trying to use silent authentication after redirecting to a page during a post-login action. According to many other posts and forums, I should be able to perform silent auth since a session with the Auth0 tenant has been established at this point.

However, all silent auth attempts are failing with login_required errors right after I logged in/redirected. Looking at the network calls, it seems that calls to /authorize are fine but I’m getting a 400 for /callback (my redirect_uri). The error on the browser simply states ‘state is missing from the response’.
