cookieDomain and Visitor ID being reset

[adam_king1]

Hi,

I have setup cookieDomain with DTM. I am finding that the MID isn't always carried to the other domain and is reset with a new one. This includes the sdid.

Is this due to load order? IE: Cloud ID Service is done before the data element is available? Can I force it to wait?

Both domains are .com.au

Cheers,

Adam

Hi Adam,

Can you send me a private message with the URLs, Company Name, and Property? I can take a look and see what's happening.

Hi Adam ,

As described by you, this generally happens when browser rejects third party cookie ( in this case demdex cookie )  Hence demdex cookie is not set on the visitor browser and every time visitor browses to different domain of same Marketing cloud  Org Id company , MID value is reset. Please check and let us know whether your browser accepts third party cookies or not.

Thanks & Regards

Hi Adam,

I tested this with the information you provided in Firefox and I didn't see an issue. My MID remained the same. This is most likely due to your browser blocking third parties cookies per Parit's response above. Which browser are you testing in?

Thanks!

Hi Tacia,

I was testing using Chrome. I've found it inconsistent, sometimes it works and other times it doesn't.

I check and Chrome settings are not blocking 3rd part cookies.

When is a data element available? Before the Visitor ID service?

Thanks,

Adam

Hi Adam,

The times that you see it's not available, is the id service timing out? The default timeout is 500ms. More information here: https://marketing.adobe.com/resources/help/en_US/mcvid/mcvid-variables.html.

Hi Adam,

Our team tested this thoroughly and we do not see an issue. The recommendation is to change the loadTimeout to 1500 and test from there. More information here: https://marketing.adobe.com/resources/help/en_US/mcvid/mcvid-variables.html

Thank you,

Hi Tacia,

are you able to answer my earlier question about Data Element availability?
