Afternoon - I've recently moved from an SE Netsweeper role to SBB and can say this doesn't sound right.
There have been multiple ways of workstation agent working in the SBB network and it has been deployed in various ways by customers. It would be great to understand the method you are currently using and go from there. The workstation agent for Chrome, in my previous experience, has been very reliable when it's setup correctly.
Feel free to drop me a PM, I'd be happy to discuss it with you directly and to show you how it should be working.
