I have been watching The State on All4 catch-up. Initially I started to watch it on a FreeSat box but the subtitles logo was greyed out. I then switched to a Humax Youview box but again no subtitles were available. I then started to watch on an iPad and lo and behold the subtitles were available and made all the difference to me fully enjoying the programme. Why no subtitles on All4 using a Humax box? They work fine on other catch-up channels.
