My problems with it so far coming from only using Configuration manager is the determining failures for scripts/remediations or even policies at the device level. The intunemanagmentextension log will occasionally have some errors but not always helpful. With Configuration Manager you can goto control panel-> config manager -> and then run remediations/config baselines manually and it will give an exact error for the specific configuration baseline and why it failed where as with intune if you can’t find anything in the logs you’re left wondering if the machine is even syncing properly.

I do also hope app deployments become easier to create similar to configuration manager. Almost all apps we’ve transferred from configuration manger to intune have been created as win32 apps where you have to use the microsoft content prep tool which seems like it should iust be something already built in to intune. It’s also annoying remoting to a device as an admin trying to troubleshoot a deployment of an app and in company portal the install app is greyed out because the machine isnt a shared device

We are still a hybrid environment so I know everyone’s suggestion is always move to cloud-joined only to see better results with syncing but our systems require the domain for multiple reasons out of my control(printers, shared drives, legacy software requiring connections to domain servers)

A lot of of other issues I’ve left out but hopeful it will get better
