To be honest you’re better off adding an external streaming device like a 4k firestick Max or android box, and then download the Tivimate Player.. TV’s are very under powered, and eventually you will start having issues with it..

Buy a firestick 4k max, download tivimate, problem solved. Unless tivimate is in the LG AppStore but I doubt it

I was able to use iptv Smarters and it worked well but I got a fire stick and like it way more

I ended up buying Google tv stick given all IPTV apps on LG market had issues managing subtitles.
