Heartbeat option doesn't work

Hi !

I enabled Heartbeat option to accurately measure the time spent on each page, especially the last page visited. As you can see in the screenshot, I enabled that option in Matomo configuration variable of the Matomo tag manager.

Unfortunatly, the last page visited still shows 0s visit duration. (Even if the option is effectively enabled, as you can see in the screenshot).

Any help would be really appreciated !

Goodday,
Clem



No one has an idea ? :pray:
