The ITV Hub webpage https://help.itv.com/hc/en-us/articles/360002766434-How-do-I-switch-subtitles-on-off- says "If subtitles are available for your show, you should see an S symbol at the top right hand side of the video when the show starts. Simply press the S button to switch them on and off." But viewing via my 5000T the S button hasn't popped up on any of the available catch-up items I have tried.
Since I can get subtitles on my computer when watching catch-up episodes on the ITV Hub, it seems to me that the problem can't be with the ITV Hub but must be with the 5000T.
Does anyone else have a similar problem? Do Humax acknowledge it as a fault? Is there a fix for it?
