I'm testing it by connecting the digital input pin directly to the GND pin on pin 8, with alligator clips. That's fine, right? If I refresh the screen, the pins stay active. I tried it with both digital input 1 and 2. Before I connect them, they show as "Inactive" in GHL connect. After connecting them, they show as "Active", even after I disconnect them. And even after I refresh the screen. If you agree I'm not doing anything wrong, I'll open a ticket.
