First of all i installed Tizen Studio.
Finally everything was ok with connection to my TV.
However i did not download anything because Tizen Studio was not able to download app for more than 58%.
OK i was not able to understand why... Tizen Studio was uninstalled and installed once again.
I received a new certificate. Tizen Studio can see my TVset, but cannot accept an app to download,
May be someone can comment what i have to do or how to arrange Tizen Studio correctly. May be i need to download any drivers or anu other software... youtu.be/BdBJcvwpJGs?si=B0IlrVrMKK1O62Mg
Thanks for your help.
