I use the VLC for Modern Windows which I downloaded through my windows app store on my tablet. I think this is the right OS.
When I'm trying to search for any subtitle, since it doesn't assume one automatically even though it's in the same folder, it doesn't work. I click on the subtitle symbol, that chatty symbol, click on 'select subtitle file', select the .srt file and when I'm done nothing happens. I don't think I'm doing something wrong since everything is so painfully simple but when I try to see my subtitle list after I select the file, there are no files selected. Welp.
