smart warp and mesh triangulate 2d. I don't know how to use them?

[Mishat]

I am back after 2 years. Been learning art more. Now I like to animate my raster based artwork. Cut out all the parts and rigging but they don't look flowy. So I tried smart warp and triangulate 2d. they are not working. I'm using 13.5.2. here's what I did:

Import transparent png image>apply smart warp> new layer created. But when I try to manipulate the points it's not working. I checked the layer setting of the image too. under image tab, smart warp layer is selected of the top warp layer. Also I tried to checked on all the display setting if i'm missing setting.

I know this is very dumb mistake. but Here i am. any step by step resource is appreciated. Seen victor's webinar but he quickly showed what's possible with the smart warp. very impressive.

Could it be you're still on frame 0?
Manipulation is applied/visible only in frames 1 and further.

Wow. That's it. I feed so dumb. Thank you very much.

You're most welcome.
And don't bother, we've all had similar rounds of practice
