Tracking information cookie Adobe Analytics

Hello, 

While testing, a tester of our clients received some notifications about the cookies that the website is using. After a discuss with the support, we identified the cookie `test_amcv_cookie_write` as the one that concerns the client. This concern is based on the fact that we do not know exactly what information is being tracked by this cookie. 

Does anyone have any additional information or clarifications related to this topic ? 

Thank you!
