Hi @ rotnasima,
See my answer above on Jan 11 to maryloumolina.
It applies to your TV model as well.
Here's a link to the [http://downloadcenter.samsung.com/content/UM/201901/20190102115403583/ENG_KM2DVBEUN-3.0.2_181205.0.pdf|user guide] for your model. Go to p.112 in the guide. Take note of the sentence which reads ''"This function may not be supported depending on the model or '''geographical area'''."''
