Hello all,

Are we allowed the read from the [System] tag provider? No matter the tag I choose to bind to, the result always appears to be null / not found.

You're in Perspective. Perspective _sessions_ don't have access to the _client_ context (we decided on this nomenclature a while ago and we're sticking to it, even if it its somewhat overloaded).

You can get access to properties _like_ what's in the `[System]/Client` folder in the session properties:

You **cannot** get the user agent (mobile phone, web browser, Workstation session) MAC address in Perspective. Full stop.

That's a little unfortunate but I understand. Thanks for the quick response!
