Why is the zone list/status not always available? It shows up for a split second and then goes away or doesn’t show at all.

The Driver only reports actively faulted zones and the list disappears when nothing is faulted. If it’s showing and disappearing then that zone is only staying tripped briefly. The driver does have a new option that allows you to define zones that are always available for bypass. This will show up as a second button below the faulted list button.
