2018 Samsung IP control is still an unknown. While there is reason to believe it will eventually work, all I have seen so far is:

(1) 1 report that standard EX-Link codes do not work. 0 reports that it does work.

(2) Multiple reports that IP control in the method of the 2016/2017 models does not work. 0 reports that it does work.

(3) Samsung has not updated their own app with 2018 model IP control yet.

I get the feeling the models just hitting the market today may not yet have some control features enabled yet. Would love to hear verified contradictory information.
