First impressions: I onboarded my android phone the day this was announced. We're encouraged by this as an alternative to options such as Lookout. Onboarding was easy enough, but it opens a persistent connection to Microsoft, and takes up far more power than any other applications on my phone (20%). It actually "overloaded" my s10 and was forced to shut down. I haven't had that happen before. Feedback has been submitted. I understand this is in preview and it will be improved before general availability. I will say that it will require a good deal of attention to power usage if it's going to be something our organization can use. Curious if anyone else has had this issue.
*UPDATE 8.6.20* - According to Microsoft: We have resolved battery consumption issues in latest build 1.0.1928.0203. We will be sharing this build soon. Please look forward for the communications on the same. If you see any issue please submit feedback thru In-app feedback with diagnostics turned on.
As expected, It doesn't include any timeline info in the security center or allow use of any of the more advanced actions that can be performed on Win 10 devices. I haven't run across anything it blocks me from accessing as of yet.
RE: Licensing. I'm also curious how that will be handled, especially for frontline workers. A standalone license would need to be made available.
