Playlist feature - How does Transition work?

Questions
1

In /wiki/JSON-API, the “Playlist object” documentation says:

transition Array of time each preset should transition to the next one, in tenths of seconds. If only one integer is supplied, all presets will transition for that time. Defaults to the current transition time if not provided.

I set a transition time of 20 (2 seconds), but see no transition time between presets. I used an array of transition times, but still see no time between. What am I doing wrong?

The syntax of the JSON command is:

“1”: {
“n”: “Playlist”,
“playlist”: {
“ps”: [2, 3 ],
“dur”: [50, 100 ],
“transition”: 20,
“repeat”: 5
}
},

I am curious as well. I am new to WLED but I figured that the transition would be just that, a slow transition to the next preset. I experimented from 2 seconds to 20 and all it seem to do was make all my lights a solid color for that duration.
