FTI Report- no access

I am trying to provide access to a user for FTI reports and getting the below error

Access ProhibitedYou are not currently authorized to use Oracle BI Interactive Dashboards.

If you would like to use this powerful capability, please contact this site's administrator.

Checks done:

1)under user manager for transportation intelligence role I have assigned operational
2)under access control list for that particular user I have provided all the related report access but still throwing the same error, can anyone suggest if I am missing something?

Thanks!
