Does KME still support the enrollment of devices using DA mode?

Yes, Knox Mobile Enrollment (KME) will continue to support UEM apps using the DA management mode. With KME, a device installs its associated UEM app via a direct URL in a UEM server.

However, UEM apps should be updated through Google Play. If Google blocks the update of DA apps through Play, then KME cannot update UEM apps using DA.
