Workaround: Add the gateway certificate's CA and intermediate certificates into the portal’s Trusted Root CA settings.

GlobalProtect® Android clients do not display Host Information Profile (HIP) notifications when the GlobalProtect tunnel is established over an IPv6 network connection. Users do not see HIP match or non-match messages, which means posture-remediation guidance is not displayed within the application. HIP policy enforcement continues to function correctly, and the HIP report is submitted and accepted by the gateway.
