PKlapwijk I'm using dynamic device groups to target Android Enterprise corporate enrolled devices, using this one dynamic group I successfully apply Compliance policies, Device Configuration Policies, Apps and App configurations.
Regarding compliance I can see devices accurately report compliance, and prompt users for resolutions both at enrollment time and using the Intune App - that said there is an issue having require encryption set on the devices I've tested, it requires that you set a startup pin but the setup phase of enrollment doesn't ever proceed and I've needed to manually reboot the device.
Device configuration policies apply and obviously are working as we've seen the results of them in the issues discussed above.
Apps and App configurations (admittedly I've only tested the Outlook app) have always been working for me even in the previous release - are you sure that you've got a "managed devices" configuration policy and not a "managed apps" policy.
