Good news! Yandex.ru support is back.
Yandex.ru support broke when they changed their interface, yet again. We updated our integration to point to the new URLs so we can still gather email addresses and names for contacts in the Yandex.ru address books.
Unfortunately, the new interface doesn’t expose phone numbers or DOB. And so we’ve dropped support for these fields from our Supported Fields sheet.
We hope that this is a temporay situation and that we’ll be able to support those fields soon.
