I found a file in /etc called astroberry.version - it says 2.0.1 - but even after numerous reboots the splash screen still says 2.0.0.
As an aside: I just tried ssh'ing into the astroberry (in an attempt to copy the above command and result as text) but got key errors - can ssh cope with more than one astroberry.local as I have a Pi3 and Pi4 set up? It seemed to say I have the wrong key.
I will ask ATIK if there is any way to get the Infinity Software to find the camera over the local network as opposed to USB on the local machine.
