The "Previous" button does not work when on a certain screen during hub installation. This applies to Intel Unite® app version 18.104.22.168.
During hub installation, on the screen asking "Do you want to configure the computer as an Intel Unite® Appliance?”, the "Previous" button does not work.
This is a known issue. The installation can be continued or aborted, if necessary, and then re-started. Please look for this to be corrected in a later version.
