Error Insufficent roles or permission
It has been observed that after enabling the GA role in the tenant , access to AIP is restricted.
The below screen shot is from the Azure Portal itself and does show that after activating a PIM role for all services in the security and compliance center the role can take up to a few hours to activate.
In the below screen shot this will confirm it is a known issue with PIM in Azure and they are working on resolving it. Unfortunately, the time delay will fluctuate from a few minutes some days to a “few hours”. Because Azure Information Protection and many other tools in Azure are part of the Security and Compliance center your access to these can be delayed.
Kindly have this fixed so as to have the deployments carried on.

Improved role activation time for Security and Compliance center functionality is complete.
