How often does it refresh?

It seems to update very few times per day. I also can't find anywhere to set preferences like which playlists, etc should show in it. I currently have many videos in my watch later folder, but it never shows any of them. It does occasionally show things from channels I'm subscribed to but there doesn't seem to be any rhyme or reason to which ones it shows. The rest of the time it just shows recommendations, but I'm not interested in them.
