Hi @Tilicho , without seeing your environment it's hard to pinpoint where the issue is, but we can try some steps to troubleshoot.
One possible reason for the extra email prompt step during the sign-on process could be that the Azure AD SSO configuration needs to be updated to reflect the changes made during the migration.
I would recommend checking the Azure AD SSO configuration to ensure that it is set up correctly and that the trust relationship between Azure AD and ADFS is properly configured. You can also check the Azure AD SSO logs to see if there are any errors or issues that could be causing the problem.
Another possible reason for the issue could be related to the load balancer configuration. It is possible that the load balancer is not properly configured to handle the SSO requests, which could be causing the extra email prompt step during the sign-on process. You can also check the load balancer logs to see if there are any errors or issues that could be causing the problem.
If nothing here works please let me know and we can open a support ticket for you.
Please let me know if you have any questions and I can help you further.
