I just installed GOS on a 7a from a PixelTablet via Vanadium. When I did that in the past, I was prompted a "Reconnect" button when flashing the factory images. This time there was no such button. Instead I had to tap "Unlock bootloader" every time I wanted USB to reconnect. I took me a while until I found out and it cost me some nerves. Do you know why this "Reconnect" button disappeared?
