    I upgraded to 3.0.1 and 90% of the time, it won't start Unity 2019.4.31f, or Unity just starts and crashes. Going back to the latest 2.x fixes the issue. The new hubs needs some serious work with older versions of Unity. The only problem now is Hub 2.x constantly nags me to upgrade to 3.x

    2.x starts my Unity 100% of the time

    One thing I’ve noticed I. The past with unity hub is that, if your on windows, it can leave processes running in the background, even when switched off.

    unlikely to be the same issue, but worth noting when installing new hub versions, to manually shut them down. This is especially true if you have multiple users on a single pc.

    not sure about Mac.
