SCCM 2012 (not sp1) Single Site
This has been happening for a while, but I've worked round it; but the "just in time" nature of stuff here has brought the issue to the forefront. User Collection with an AD Security Group as a member. Advert targeted at that collection. Advert may take 12/24 hrs to appear in the Application Catalogue. Querying the group in sccm, reveals all the users who are members, there are no backlogs in discovery processes and everything looks good. Any thoughts on why the delay, or where to start checking?
