Editing a segment
You can't add your own data to an existing segment that's based on uploaded data. You can only create a new segment and replace the previous segment with the new one in your Yandex Direct ad settings.
Still have questions?
Customer service specialists can advise you only on the ad campaigns linked to the login you are using to contact them. You can see your login in the upper-right corner of the screen. The specialist will get access to your data only when processing your request.
