On my Zgemma H9 Twin box i've always had problems with subtitles. I usually have to switch them off and on a few times to get them to work and often even that doesn't get them to show. If they're embeded into the file or external .srt I have difficulty with them either way.
well maybe the new change (see above) which will be in a later build, will fix issue. Try it and see and if you still have issues then you need to post a test file I can use.
