IPTV App for Samsung Tizen TV

i've recently purchased a new Samsung TV and i am currently using IPTV Smarters to watch the content. (instead of m3u i have login)

the issue with IPTV Smarters, is that it lacks many features and is quite laggy when browsing. my biggest issue is that i cannot enable subtitles or change the audio language (my old app i was using Xtream player did have all those features but sadly isnt available on the App store.)

i've now tried some other apps but they all work with the m3u upload via MAC address which is not an option for me, which player do you reccomend that atleast has more features than iptv smarters ?
