We've been fairly actively testing versions E86.70 & Newer due to their added support for 22H2 (albeit still EA).
We had recently noticed an issue relating to Threat Hunting; we only have records for "Detection Event" and "Network" sensor categories and even in those departments, the numbers are significantly lower than what we'd typically see in prior versions.
And this is consistent among ~300 installations of these newer clients.
Within our statistics pool, E86.60 still appears to function as expected in regards to Threat Hunting delivery. A check was also performed with "checkconnectivity.exe" and on E86.80, which is our largest sample size, the 3 URLs associated with Threat Hunting Upload all appear to fail.
We've upgraded a handful of clients to E87.00 and the connectivity check now appears to succeed, but we're still not receiving events to TH, though the sample size here is still fairly small.
Is anyone else experiencing this?
