Hi all,
We have an application that is using Azure AD B2C custom policies for sign up and sign in flows. Users are experiencing an error which appears when a logged in tab is closed without logging out and then attempting to log in in a new tab in the same browser. This issue only appears in our UAT tenant and not in DEV, QA or PROD. I have attached the error message. This issue also persists in an incognito browser. I am wondering if anyone has experienced this before I open a ticket. Any guidance would be appreciated.
Thank you,
Ciaran.
