Mongolia adopted Cyrillic during its early communist years which saw heavy influence from the USSR. They started adopting their traditional script in schools again a few years ago, but the older people didn't know how to read or write it unfortunately. I saw the traditional script being used sparingly in Ulaanbator around 2017 but as for the rest of the country I don't think I saw it at all, except in Buddhist temples (which were also mostly destroyed during the communist era unfortunately).
