Hi Christian, even these changes are also not working for me.
Assign those specific users to BI CONSUMER Role and assign this role to the dashboard. Permission for this role should be "OPEN".
That is, create a new role by inheriting BI CONSUMER role and use it in this dashboard.
Alternatively, you can add those specific users directly into this dashboard with permission as "OPEN" --> Not Recommended, but can be used for Testing/ verification purpose.
You must a LOT more specifc.
WHAT EXACT app roles does the user in question have?
WHAT EXACT permissions are set on the dashboard?
We are not in front of your system. We can't magically know what's configured and what's happening. A problem isn't explained in 2 sentences.
