Just upgraded from MR3 to MR4 and found one issue.
Manual Pattern Update in airgap environment doesn't work anymore. I can confirm that it worked on MR3.
Uploaded the actual pattern file in WebGui but nothing happened.
Also there is no entry in /log/u2d_airgap.log
That sounds like an issue. Can you open a Case and link the Case ID to emmosophos ?
I will open a case in January and let you know the case ID.
