Thanks for helping!
I'm using Linux Mint 19.3 Cinnamon, the nano is connected to my laptop via the y-cable. I am using Firefox 74.0.
If I use live and 30seconds, then after the 30 seconds it shows me the results. If I use live and then continuous it wouldn't.
I updated to 2.7.0 from a very old version (sorry can't remember which) and have been solving all kinds of problems like mounting the SD card, the wp6.sh connection script not working. In the end I tried factory reset pressing the button untill reboot but when I surfed to the UI it accepted my old root password. I had to use the configuration / general button to reset it.
Now it updates the list every 30 seconds or so when on Live and Continuous. Is this the normal update frequency?
