Hi Team,

We have a site A,B and C where the tracking is enabled. For the site B, we have set the user id. We have a link in site A to navigate to the site B. When we checked the visitor id, it's different for the site A and site B. But the visitor id is matching for the site A and C. This issue is happening mainly in the IE.

Could you please help us.

Hello Vinuta,
this is how it works at the moment. Setting the user id will overide the visitor id with the user id.

Hi Michael,

Thanks for the response.

Currently for the site A the visitor id is 86fd7df26786a7d9 and for the site B it is 82065ac2e99ec62f. This remains unchanged for the different sessions in Internet explorer. But my colleague has added the site B as trusted site and the visitor id remains same for both the sites(293efb0e9eb29564).
We have the below configuration
use_third_party_id_cookie = 1
trust_visitors_cookies = 1

Is there a way to do the settings so that the visitor id appears same for both the sites.

This was fixed and now the visitor IDs are not tied to the user id anymore. see: https://github.com/matomo-org/matomo/pull/14360
