I am testing some DLP features on Cloud App security using conditional access and session control policies.
The idea is to block file download and share on non-managed devices for browser access.
This seems to work on IE, Chrome & Edge but doesn't work with Firefox i.e. devices using Firefox are treated as non-managed even they are managed.
All the policies work fine with IE, Chrome & Edge and i am able to differentiate between managed and non-managed devices and correct policies applied.
Anyone who has encountered such a problem before? Any Fix?
