Have been using Express IPTV with STB Emu on my Firestick. Love the variety and quality.

Only thing I am missing is being able to load subtitles on movies. Eg with Kodi I had Podnapsi and Subscene add on and I could search and load subtitles.

Either for Firestick or LG WebOS or a dedicated box is there any app that lets me use Express IPTV subscription with subtitles.

Thanks
