PureEngage On-Premises

Hi,
I have issue in the WDE. After adding Favorites it's displaying for the first time then if i exit the application those added Favorites not displaying. Please help me to fix this

Do the agent have sufficient privileges to store favorites onto their objects within Genesys configuration? What say WDE logs? 

It's says insufficient permission to perform this operation after exit the application.

It is pretty clear - missing permissions (CRUD) on person level for agents/supervisors.
