Currently,security roles assigned to users can be exported from "Reports" or "Advanced Search".
However, security roles assigned to apps cannot be exported.
It is possible to check the security roles by opening "Manage Roles" for each app, but it is not efficient.
Customers say that it would be more efficient if there was a feature to export security roles for apps as well as security roles for users.
Customers think the implementation of this feature will make Dynamics 365 (Online) more useful.
