Azure Tenant B2C Custom policy login issue

Hi all,

I'm facing an issue with B2C Tenant Login when I access directly to the old login B2C Tenant page ( "/my-page/b2c_1a_signup_signin/oath2/v2.0/authorize?client_id=...&scope=..." which has expired value of client-request-id, code_challange and nonce. i think ) instead of accessing from my project Home Page. Because of the value of client-request-id, code_challange and nonce were expired so when I enter verified code, Azure dont know where to redirect when the verification is finish. And I have found a solution to solve it, that is to clear the cookies when ever the issue is occure. Does it has any property to do that inside the B2C custom policy?

Thank you
