I am pro user
Sometimes when i search for subtitle i cant find it in your default search engine
But when access opensubtitle i found it there
Can i use more than search engine in infuse
I use apple tv 4k latest infuse version
Welcome to the forum!
Infuse only supports OpenSubtitles for subtitles in the built in search but you can always download subtitles on another device from any other source and place them with your video file and access those with Infuse.
You can find out how to do this here
