I've been trying to sync security groups using Entra Connect, and while users and devices are syncing perfectly, the security groups just aren't showing up in Entra ID. I've double-checked that all Organizational Units (OUs) are configured to sync in the Entra Connect settings. I even added the AD Connect group to the Security Groups, but still no luck. Anyone have any ideas? AI couldn't figure this one out, so I'm turning to you all for help!

I've seen this issue a few times. Verify that those groups are universal and not domain local, as that trips a lot of people up. It's also a good idea to check that they aren't mail-enabled or filtered out. The AD Connect logs can provide some insights too.
Have you looked at the prerequisites and the types of groups that don't sync? It’s worth checking the guidelines from Microsoft's documentation regarding Azure AD Connect sync. That might give you some clues.
Make sure the group is universal and not mail-enabled. Also, check if there are any group filters in place and try forcing a full sync. Groups can sometimes get skipped if they’re empty or if they're structured in a nested way.
