The Umbrella Chromebook client does not yet include all of the functionality that the Umbrella Roaming Client offers, and thus has limitations on its policies. Chromebook policies cannot contain:
- Block Page Bypass (BPB) configuration
- Custom Block Pages
- Intelligent Proxy
Otherwise the Chromebook client will fail open and erroneously log the request as a block.
