Heart beat not working?

I’m have the HeartBeatTimer enabled per: JavaScript Tracking Client: Integrate - Matomo Analytics (formerly Piwik Analytics) - Developer Docs - v3

However, the users are still listed as having spent 0s on the page. Is there additional configuration that is needed?

This may cause by the user has reach and interact less than the interval has set (15sec ? 30 seconds?)


HeartBeatTimer doesn’t work anymore. It seems to be disabled in one of last versions. I already asked for but got no answers.


See here for a potential reason why heartbeat might seem to not work anymore (but still should record the same data):
