Subtitles .srt

I am new with Apple tv 4, so i download infuse (not pro, yet), and i am trying watch my movies from my router (smb, with usb drive), so the subtitles doesn’t appear ? Any help, is it right ? How can i watch movies with .srt subtitles. P.S. movie and subtitle are with the same name and in the same folder.

Have you swiped down, and chosen the subtitle?
