The historical data for what period does OWOX BI export from Yandex.Market?

For the Start, Marketing Data, Reports & Attribution, and Enterprise subscription plans, after you have set up the Yandex.Market→Google Analytics data export, OWOX BI exports historical data for the previous 30 days.

OWOX BI can't export more because Yandex.Market stores historical data for the previous 30 days only.
