Where is "Chrome / app" Traffic Coming From?

Overview:

Seeing traffic attributed to "Chrome / app" in your Source/Medium Report?

Here's what's happening:

Say a shopper is browsing your website on Chrome > adds something to their cart > and then abandons their cart.

When that shopper opens up a new Chrome tab, they'll see a section titled "Your carts"

If the shopper clicks through that link, they'll be taken to their abandoned cart.

To take credit for any future actions/purchases, Chrome adds UTM parameters to the link so the shopper's new session will be attributed to Source = Chrome, Medium = App, and Campaign = chrome-cart
