Thanks for flagging. The change that caused this has been rolled back, and the Names behavior for GetFriendsOnline will not change with the deprecation changes detailed in Updating Friends API & Deprecating IsOnline property from GetFriendsAsync. The issue was related to sequencing rollouts for that.
