Android device dropped off InTune

Hi we have some corporate mobiles enrolled in InTune. I have recently noticed that some had not checked in for a while (probably because turned off) so had fallen out of compliance and they have suddenly dropped off the list of devices. We don't have the device tidy up option turned on so nothing gets deleted automatically, however our config policy stipulates that after 5 bad passwords they get wiped.

I'm yet to hear back from the users, however I cannot find anything that would confirm this in the logs.

Anyone know where I can see this and confirm this has happened?

Thanks

Neil
