at_check cookie behavior in opt-In feature

[RitendraS11]

Hi Team,

I have implemented the Opt-In feature (Using oneTrust) on one website and I can see that at_check gets created even if the user didn't provided consent - on page load. It means that the at.js gets executed before the oneTrust script executes.

In oneTrust, we have configured at_check as an analytical cookie.

NOTE: I have enabled opt-in in the adobe target extension in data collection.

My query is: Should the at_check cookie be considered as an analytical cookie OR an essential cookie? Also, how does opt-In work with Adobe target on the website?

As per the documentation, I found the below info - 

at_check: This cookie gives us the ability to test which content is more relevant to you, and show you personalized content based on your behavior.

Any information on this direction will be highly appreciated!
