Hier die Fixes beim normalen Rollout:<\/p>\n<ul>\n<li><b class=\"ocpLegacyBold\">[Application Control for Business]\u00a0<\/b>Improved: This update improves Application ID tagging in Application Control for Business policies. With this update, the system identifies which apps should receive tags more accurately and behaves more reliably.<\/li>\n<li><b class=\"ocpLegacyBold\">[Narrator]<\/b>\u00a0This update improves the Natural Voices experience in Narrator.
