I have migrated one of the client implementation from Adobe Dtm to Adobe Launch. I could notice that all the extensions are migrated as expected. But, I don't see that Experience Cloud ID Service is not working as expected on the website.
What could be the issue for not firing and please do let me know how to mitigate this issue.
If Experience Cloud ID extension is configured in Launch web property with correct Marketing Cloud Organization ID, then "mid" parameter will be generated in Adobe Analytics server call for your website successfully.
