How do I allow a user access to a dataset that is signed in with a cross account

Previously I was able to add IAMROLENAME/QuicksightName to my RLS data set to be able to view all the data:

UserName, Partition

This worked on older dashboards, however, since new dashboards have the v2 RLS setting, this no longer works. When I log into AWS with a cross-account role, how can I view a dataset secured with RLS in my analysis?

Hello @Mark-Hayward, I am wondering if the permissions for the dashboards that were created with the v2 RLS setting are different. Maybe your IAM policies or policies for those dashboards need to be updated to allow IAM Role users to view them. Here is some documentation regarding IAM role access with QuickSight to help you debug this issue.
