How it should behave now, when opening a post: * Scroll down to reach the comments, the top menu bar will disappear and will be replaced with the sticky post header. * Scroll back up to reach the post content, the sticky title will disappear and top menu bar will show back up. * Create a comment or reply to someone, the sticky title will disappear up until you're done replying or tap cancel. ---- **So for those of you who got it disabled in user preferences, give it another try. It's now working as intended.**
