My web app doesn't need signup feature. So i am only looking for signin. So i didn't setup anything under signup or sign policies.
I am trying to add custom login page to signin policy in Azure AD B2C. I selected Local Account SignIn as Identity provider. But the option Page UI Customization is not enabled and a lock symbol is shown. There is no validation message or information or tooltip explaining what should i do to unlock this feature. But this feature is enabled under signup or sign policies blade.
Can somebody help me with this.
