Multisite installation tracking code

Hi there,

I’m running the WP-Matomo plugin on a multisite installation in not network-enabled mode. The tracking works fine and I get the datas correctly.

I’m sorry if it’s a dumb question :
On every website’s source code of this installation, I can’t see the JS tracking code, or the link to matomo.js… how is it possible? I’m a bit confused.

I have no console errors, the tracking codes are different into their respective WordPress administration settings.

Thank by advance for your help.
