2509 Hotfix Rollup (KB36949461)
https://learn.microsoft.com/en-us/intune/configmgr/hotfix/2509/36949461
Just saw this in the console today - Was it just released? Date shows 4/14 but I know I've checked since then and it wasn't there.
Going to apply later today. Been having unexplainable client issues all the past couple weeks after upgrading to 2509 and this seems like it may be the fix. Fingers crossed.
What I've been experiencing, client communication seems to be working but it's been passing bad info, compliance and application reporting failures spiked. Previously compliant devices for things that wouldn't change were reporting non-compliant with a message of "success" or " already compliant" as the category in the error section. Application installs are failing because they are pointing to the wrong folder in ccmcache. About 33% of my devices seem to be affected. Only way I've been able to resolve is to reinstall the client.
