, I am getting "Akeeba Ticket System - An unhandled Exception has been detected" when accessing the "Latest Tickets" menu item when logged in as a case manager.
This is a known issue. An update is scheduled for Monday to address it. Meanwhile please rename components/com_ats/tmpl/Latest to Latests (note the trailing s at the end).
Additionally, I noticed a message indicating that FOF was newer than the upgrade.
Correct. Akeeba Backup and Admin Tools have a slightly newer version of FOF (4.0.1 instead of 4.0.0). As noted right below that message this is not an error, it is normal to occur but Joomla will not let us suppress this message).
Lastly, I also noticed that in Extensions>Manage>Discover shows that one of the plugins is still on 3.5.4 (see screenshot)
This looks like a leftover XML file with the wrong plugin name in it which was, indeed, shipped with 3.5.4. We have fixed the plugin since then. I believe that if you try to use Discover to install this broken XML file you will just get an error.
