Hi, Just purchased a PanTiltHat from you and trying to set it up with a new RasPi 3 B+ following the how-to instructions on your website.
Started with the recommended curl … | bash command which then ran so far but terminated with error messages about apt indexes.
Then tried to install the Pimoroni Dashboard. This seemed to go well and appeared in the Accessories list. Clicking on it just gives a brief screen flash of a possible dialogue then nothing (just desktop).
As this is a new RasPi it was set up with the supplied NOOBS card which installed the latest Raspbian Buster OS.
