This is not a PROMO CODE, you purchase an invitation link to the Yandex family group.
The Yandex Plus subscription is activated using a unique code received by you through the support service, detailed instructions are attached.
The subscription is provided as an invitation link to join a family group.
The invitation is connected only to 1 account, you will not be able to add any other profiles/accounts/family/loved ones to this subscription. You will not be the administrator of the family group, you will be a member of the family. If you already have a Yandex family subscription, you are an organizer or a member of a Yandex family group, then you will have to log out of your family group when you activate the invitation.
You do not need to link a bank card (everything has already been done for you, the subscription has already been paid), and money will not be debited from you at the end of the family subscription.
If you have a valid Yandex Plus subscription, it will be suspended and renewed after the end of this subscription.
