Before Unity Hub, it used to be the case that if you opened up a project that was from an older version, you would be prompted to upgrade the project. I am now on the latest Unity Hub 2.0.0 and I am trying to open a project that was last saved with 2018.2.1f1 but I am unable to. From installs, I am able to download and install the closest available version, 2018.2.21f1, but anytime I try to open my project I get the message Missing editor version 2018.2.1f1 on this machine. Select another version from the list or install the missing one. How can I upgrade this project like we did in older versions?
