I have a doubt regarding this HC article.
I don't understand what does it mean that I can "also create an use your own identifier"
- Why a developer would want to use its own identifier and not the GA one?
- Which are the benefits of this decision?
Thanks for the shared information.
I only have a doubt: I know that if I install the default cookie (CLIENT ID), I will be able to see the devices and browsers from the visits. Because I did it in the past. So, isn't that the main difference (advantage) with the USER_ID cookie?
Why would I need the USER_ID if I do have the metrics with CLIENT_ID?
