Subtitle delay

Really loved to see that new feature of sub delay but once I upgraded to 1.5 I don´t see any option to do that.  I´m still on 4.4.4.  Could that be an issue.

Subtitle settings can be adjusted through the Playback Menu while a video is playing.

This menu can be accessed by holding the center (select) button during playback. Full details can be found here.
