When will the difficult rating of the problems from the recent div2 and global contest be updated? @MikeMirzayanov

Hi guys, I am creating a slack group, where we can give VC everyday and discuss interesting problems and improve together. Currrently I am accepting people rated between 1400-1700. If you want to join DM me and comment here, I will share the link to the channel. We can mashup problems from several OJ's and discuss strategies for improving.
