I just completed a reinstall on my Mac running Catalina. For the life of me I cannot figure out one thing in the mac mail app. I cannot figure out how to see my individual folders under my mail account. I have rules set up with my account on my mail providers site to have messages go into folders. How do I get the mail app to let me see those folders? Right now I see the main inbox for the account but not the individual folders under that account.
