@ Jackie,
Yes, I set up both plugboards as directed....just went back and made sure they were correct.
I wiped everything off the device, connected to calibre & "sent" books to the device....all worked like a charm.....the T1 displays the series metadata as I wanted. I then disconnected the device and reconnected. I waited a few minutes and disconnected the device.....the series metadata disappeared from the device.
I have disconnected & reconnected several times, but the series metadata does not reappear.
I'm not sure what else to try.....any ideas?
