    Amazing. The performance fixes keep coming! Great news for problems support indicated as never reported by other customers and non reproducable when you open cases for Media composer 2020.x/2021.x. And now convince customers to start the testing all over again. 

    Now backwards compatibility in Mediacentral cloud UX 2022 with 2021 mediacentral products and we can start moving forward.
