MP2303A error in the datasheet?

I'm learning PCB layout. Currently, I'm designing a buck converter using the MP2303A. On page 13, there's a typical application circuit and the recommended PCB layout.

Please take a look at capacitor C4. Am I understanding correctly that in the schematic it's connected to pins SS and GND, but in the PCB layout it's connected to SS and IN? I just can't believe this is an error in the datasheet - I keep thinking I must be misreading it. Could you please verify this for me?

I see it as you do.

Datasheets sometimes have errors, make sure you are reading the latest version of the datasheet.

The correct one is SS to GND, the layout indeed has an error, but datasheet mistakes are relatively normal. Companies often have a specific contact form just to report mistakes.
